Handset Manufacturers: Who are we kidding with the anemic smartphone batteries?

By | December 16, 2011, 10:09am PST

Summary: Do you seriously expect me to go all day with a battery that can realistically keep a 4G phone powered for four hours using default presets?

Yesterday, I took the plunge and used up one of my line upgrades on my Verizon Wireless account on a Samsung Galaxy Nexus. My wife, who dutifully went to the store yesterday to pick it up for me when I was away on a business trip got my current Droid Bionic in trade.

I’ve only been playing with the Nexus for a few hours, and I happen to think it is a great phone, but it is yet again another of the latest crop of smartphones that all have the same exact problem: an anemic battery, with a whole 1850 milliampere-hours (mAh) to keep this hungry 4G phone with a super-bright AMOLED HD display running all day.

This has been going on for years, ever since I started using smartphones with my original Blackberry Bold 9000. If you want a whole day of uninterrupted use without having to top off your charge, you need to go buy an extended battery instead.

The ones that come with the phones just aren’t good enough, and I’m including Apple with their ridiculous sealed battery compartments in this complaint too. A whole 1400 mAh to run the iPhone 4S for a full day of use? Seriously?

And Motorola, just what the hell were you thinking when you designed an ultra-thin 4G Android phone with a sealed battery compartment with the Droid Razr? That’s like building a Lamborghini with a 4 gallon gas tank. It’s not going to go very far.

A whole industry of smartphone accessories from 3rd party battery manufacturers has cropped up in order to deal with this problem. SEIDIO Innocell is one of the more well-known companies and they produce huge Lithium Ions for most of the major brands and carriers .

For example, the ones that they produce for the newer 4G phones are in the 2800-3500 mAh range. These are all pretty much guaranteed to keep a phone running in 4G mode running for an entire 8 hour business day with moderate usage.

And if you drop your phone down to 3G and only turn the GPS services and the email sync on when you need them, you can keep it running around 16 to 20 hours with one of these batteries.

Still, I don’t understand why we need to have default anemic batteries in the first place. I understand the desire for manufacturers to keep handsets thin, but let’s face it, this is getting ridiculous.

A lot of this has to do with Apple driving the industrial design ethos that everyone is now competing with, but I find that Apple-envy ideology in order to attract customers when it comes to phones a bit nuts.

I mean, the entire auto industry doesn’t try to make all cars look like Ferraris. So why should every smartphone strive to be ultra-thin? How can you reasonably expect a day of life out of a 4G, let alone a 3G phone with heavy usage with a battery with less than say, 2500 mAh?

This is doubly infuriating because the first thing that I do when I buy a new phone is want to put in a bigger battery. In the case of the Galaxy Nexus, Verizon offers a Samsung OEM 2100 mAh battery to replace the default 1850 mAh one.

That’s what, a whole 250 mAh improvement? Why isn’t that the default battery in the first place?

After you’ve bought your extended battery, you now have to figure out how to get it into a protective case. This is even more of a problem, because companies like OtterBox (my case vendor of choice) only design their cases for the default battery, not for 3rd-party batteries, or even the extended OEM batteries offered from the carrier.

I also went through this issue on my Droid Bionic — Motorola offers its own extended battery, the 2760 mAh BW8X. But good luck finding any 3rd-party case that fits it.

Until battery chemistry improves to allow thinner batteries to hold a much larger charge, the only solution to battery anemia is for the handset OEMs and the carriers to finally face up to the facts that trying to sell a thin phone with a battery that isn’t up to the task is doing a huge disservice to the customer.

And that may very well mean sacrificing the “I want to be like Apple” ethos and giving us bigger batteries and somewhat thicker phones by default.

Don't know why it's so hard for people to understand how business works. You give the customer the least you can for the most money you can get away with.
Every new phone could have 4GB system memory so it's not constanly bogged down, Dual core procs, the most amazing screens, etc. Then what will they put out next month?
"Slimness" has nothing to do with it so if you mentioned Apple or Razr as the epicenter of battery shrinking then you're just a troll. Technology just gets smaller... Brick phone vs StarTac anyone? It doesn't matter if it gets slimmer, shorter, or narrower. People want smaller and expect no tradeoff.
It's an obvious reality that a smartphone needs to be plugged in every moment that is available. When I sit at my desk, plug it in. When I'm in bed, plug it in. When I'm driving, plug it in. Inside that tiny little object there's a Processor, RAM, Bluetooth radio, WiFi radio, GPS radio and a display and people think it should draw energy from the ether and run forever.
Interesting how you blamed your Android handset battery woes on Apple. Wasn't Motorola's initial Razor cell phone the genesis for your thin industrial design ethos?
@kenosha7777 We're talking about smartphones here which have much higher power requirements than a simple dumb phone.
@jperlow

Are you calling my trusty old phone "dumb"? Grin.

I anticipated and understood your points, Jason, even before I posted my initial comment. But my point is still valid in that the modern industrial cell phone design, which places an emphasis on thinness, began with the initial Moto Razor.

By the way, Apple has taken a lot of press flack over their decision to eschew incorporating 4G technology into their iPhone 4 and 4s models citing battery charge duration issues using current 4G chip sets.

However, using current technology, I have read that handset manufactures were more or less forced to create a larger handset in order to incorporate a larger battery that would supply minimal accepted 4G duration times. The larger display screens used in these handsets were not a response by primary end users requesting a larger viewing area but rather a design consequence resulting from a case designed to incorporate the larger battery.

Personally, you may have been better off choosing the 4S (or any 3G handset) rather than a 4G enabled phone until the technology catches up to the dream, so to speak. (In much the same way that your fellow ZDNet bloggers, AKH, James and David have chosen to do.)

@jperlow

Yes, the Razr set the stage for devices that targeted form instead of function, but even so, it had several days of standby time with the battery it had.

My single biggest question that tangentially targets battery life is this: Why do apps start by themselves in Android? Yes, running some sort of system service is a requirement for certain things (push e-mail, the BBM clone apps, alarm clocks, etc.), but why is there no facility that prevents apps from starting by themeselves? Certainly bundling something like msconfig into Android would help, right?

Joey
@jperlow problem is Apple batteries does not even last that long. Not to mention Apple does not have 4G too... For God's sake, please stop binding everything to Apple-envy because there is none...
@voyager529
I have a rooted Nook Color and I noticed this problem of apps Opening by themselves. It comes down to the App Creator they make it so it will do this when it's installed (For all kinds of things most harmless some not so harmless) I hope Google will add an option to have an app auto start or not, Until they do that I will just use the System Tune app to disable the auto start of apps or just uninstall the apps completely.
@AmediaN problem is Apple batteries does not even last that long. Not to mention Apple does not have 4G too... For God's sake, please stop binding everything to Apple-envy because there is none...


Really? I must have somehow gotten a supercharged iPhone 4 because my battery lasts 2 days before I need to charge it - and that's with phone calls, emails, texts, foursquare check-ins, Facebook, and playing solitare or scrabble while waiting on the slow elevator. In comparison my Samsung Fascinate lasts less than a day. And YES there is a lot of Apple envy - it sucks but it's there nonetheless.
@Pete "athynz" Athens

2days? You must have the compacto super duper battery maxx model!

Dude, you need to stop looking at it and use it.
Moderate use never had any iPhone last 2 days.
Now my i4 on iOS 5 won't last over night unless plugged in.

2 days..... Wow
@Pete "athynz" Athens seriously mate? Galaxy S II runs over 3 days straight with your usage. You must be halucinating about iPhone 4S, cos I also have one there...
"If you drop your phone down to 3G and only turn the GPS services and the email sync on when you need them, you can keep it running around 16 to 20 hours with one of these batteries."

You can anyway or there about. An Android phone should last about 12-15 hours with moderate use (the so called "day's use"). We've not got 4G here and it sounds like America shouldn't really have it either, batteries cannot cope.

I 100% agree they need to stop with this obsession on making phones slimmer and slimmer. Many extended batteries aren't much thicker and I know most people would prefer a battery that truly lasted a day (24 hours).

It won't happen though. The public now expects slim phones.

p.s - I've never used a phone case. I prefer to look after my phone.
@Joey: I don't really buy it but Android is supposed to self-manage and dormant apps aren't supposed to use any battery power at all.
@bradavon

My HTC HD2 running Windows Mobile 6.5 will get me through a day on a standard capacity battery. My other HTC HD2 running Android with similar usage patterns will get me through most of the day on a high capacity battery.

I'm open to alternative explanations.

So far I have been really pleased with my SG Skyrocket.
A good power management system seems to really help.
After using an iPhone for a while, I have unfortunately, become very adept at "sipping" from notebooks etc... to allow full day use.

For phones I have put an extended battery into, due o the case issue (as in lack of) I find if I wrap it in a Gelaskin it does really well. (Note:textured backs may have issues with these)
Jason, it is not all about you. Smaller batteries are used because most consumers don't need anything bigger, and they are cheaper. Case manufactures produce for the rule and not the exception. As for the sealed battery, I have come to the conclusion I would rather use a battery case rather opening up my phone every time I wanted to change batteries. Much less ware and tare on the phone that way as the battery doors are not really designed to be opened and shut on a daily basis.
I am sorry to be one the one that has to tell you that the world does not revolve around you. Decisions are made every day with no thought of how Jason would like the world to be.
@jhuddle Really I was under the impression that EVERYTHING was about me. I guess you learn something new every day. Thanks man!
@jperlow No worries I'm here to help. In all seriousness its about the economics. There are alot more batterry/accessory options for iPhones simply because there are more of them with fewer form factors. Makes life much easier for third party manufactures to realize enough market to make the stuff you are looking for. Maybe that should enter into your decision making. It did for me.
@jperlow


I suggest you get over your Windows blindness and try WP7. Yet to find one that didn't last 2-3 days. But then that's what I'd expect of a software developer, rather than your favourite advertising and packaging companies wink
Its not about replies its about opinion
BTW Nokia Lumina 800 runs 2 days all turned on
Admittedly its not 4g...
@jperlow
@jhuddle BS most consumers don't need anything bigger. The biggest complaint I ever hear with any phone usually boils down to "God, I just charged this thing and it's already dead".
@Aerowind That might be the most complaints you hear, but you only hear that from the power users, who end up being a relatively small group. Hence most users don't need the bigger battery. Most people can plug thier phone when they go to bed and they are fine for the next day, some might charge in their car on the way home or on their way out for the evening, but that gets them through.
If most people needed the larger battery, then most would want a case to accommodate the larger battery, and we would see more cases for larger batteries than for the stock battery. That is just not the case. Look don't bite my head off I'm only telling what the market has said.
Out of the 150 phones I support, only three have extra batteries. Why because they are the only ones who need it.

@Aerowind
Also about mid afternoon at work it's the "hey! Can I borrow your charger?"

@jhuddle
What do you consider a power user? I work with engineers, management and consultants mostly and they run the gammit of smartphones. The majority need help by mid afternoon. On a late day we all do by evening.
I pack a spare charger or battery for those times. Have used a spare battery pack (XtremeMac ) but it's not holding up like I hoped.
@jhuddle

Unfortunately, battery complaints are not exclusive to power users by any means. I have an EVO and prior to installing and training Llama, I couldn't get much past lunch without charging. I'm far from a power user, in terms of quantity of use, at least. I rarely make calls (1-2 brief calls per day) and pretty much only use it to check e-mail and maybe do a little surfing/reading while on smoke breaks.

And that's been the feedback from pretty much any 4G smart phone user I've gotten feedback from. It's not just those that have the thing glued to their ear and/or hands all day long that experience the battery woes, it's just that there's little alternative.

PS - I highly recommend Llama to any Android user. It can eliminate (or at least minimize) the "toggle dance" from your daily routine. Such as, toggling audible alerts on/off based on time of day, toggling wifi, bluetooth, 4G, etc. on/off based on location, etc.
@jhuddle

I disagree. I am not a power user and my original droid incredible could barely last a day just sitting in my pocket. If I started texting or made one call, half the juice would be gone. After about a year I had to buy a higher powered battery to replace the crappy oem one. I still use my phone about the same but now can go about 2 days with juice defender depending on how little I use the phone. Of course the case I purchased and the original battery cover didn't fit so I had to purchase more crap for the over rated droid incredible. I can't wait to get to the end of my contract. I don't see myself with another droid that is for sure.
@hopp64 I feel your pain. My only point is that your experience is not typical. In my experience all phones HTC droids, iPhones, moto droids, blackberries, experience similar battery life. I manage 150 device of all makes and models. Only three have extended batteries. Most people easily get by with the stock batteries.
Maybe your original battery was defective, or you send alot of time in areas with bad coverage, I don't know. But your experience is not the norm.
@jhuddle

Funny, most of the complaints about smartphone users is that the battery life is shocking. In fact, I don't know ANYONE (from mums, managers, doctors, etc) who is happy with their smartphone battery life.

You statement that most consumers don't need more battery rings completely and utterly hollow I'm afraid. You either don't speak to many people, or you chose not to hear what they are saying to you.
@jhuddle - have you ever looked at the prices of higher AH batteries? They cost $10-20, not even wholesale pricing... Your price argument is moot.
He has a valid opinion about using the phone over a reasonable period of time without having to charge it, but apparently your opinion has more weight than his? XD
@jhuddle First, I will point out your grammatical mistakes: ware and tare are nouns; wear and tear are verbs. Since you seem to need it, I recommend you go to theoatmeal.com and click on the grammar tag at the top for help with your writing.

Now to the argument: Mr. Perlow is only expressing the sentiment of people who (even moderately) use their smartphones. My new Samsung Galaxy S II is not 4G and the battery life is still terrible. If a power user buys a high-end phone they'll be damned if they get anything less than the best. It limits the usefulness to have a small battery. If someone cares so much about having a slim phone, speed and battery life are probably secondary considerations (they are, after all, buying on looks). With the plethora of phones available, there is no good reason to not have a top-tier phone with excellent battery life.
Also, why is there such a large market for iPhone battery cases if the battery life is ???good enough????
@thehumanyawn ah the grammar police. You got me.
All I am saying simply this. The standard batteries are good enough for most people. I do not recall ever stating good enough for all. There are definately some people who need larger batteries, not most, just some.
There are two reasons we see extended battey packs for iPhones. First some people need them, some not most. Second is that there are only a handful of form factors for iPhones. This is an important distinction between droids and iPhones. For arguments sake assume that 10% of all phone users need an extra battery. As a manufacturer I can look at the iPhone 4 market and say if I get 10% of that market I can make money on a battery case. In the Andriod world I have to make several different size and shaped cases to reach the same number of units. It is just not worth it for Andriod handsets. If 80% or 90% of users needed larger batteries then we would see cases for them, but we don't. Why? Because most people do not need extra battery life.
We can argue over the percentage of users who need extra batteries but judging from the number of cases available to fit them that number is relatively small. At the end of the day the reason there is not a top tiered phone with excelent battery life is that the market will not support it, or at least that is what all of the manufactures believe. I would venture to guess they are correct, current battery life is enough for all but the power users.
P.S.
Can someone get my eighth grade English teacher on the line, so I can get another grammar lesson? Never mind the battery on my phone just died...
I've been saying this for a while now. They're underpowered to begin with, on top of the constant recharge cycles that degrade performance.
deleted by STEELHOOF. BAD POST.
It is not so much the battery. Until we can get a new type of battery storage medium to replace lithium-ion or nickel???metal hydride, there is a limit to the Joules that are available per cc. The real design issue I ran into was the power consumption.

RF is energy intensive directly related to the antenna efficiency and the delivered power necessary for phone calls and the exchange of data for uploads and downloads to the internet.

Add to this the energy to perform computations like translating binary to pictures and or sounds that are necessary to the smartphone experience... power consumption.

I suggest it is better programming code, codecs requiring less CPU, and higher efficencies in antennas & displays that are the solution.

this is why my cell phone is as dumb as I could get and a battery charge lasts a few weeks. So much about phone progress...;)
I'm hesitant to lay the blame on the battery as I'm running Cyanogenmod on my HTC Inc and I get a full 2-2.5 days on a single charge with the stock battery. From what I've seen it all has to do with the default configuration on the device. It can be optimized for better battery life and this should be the default.
Funny you should post a picture of the brand-new Samsung Galaxy Nexus just released?

Oh my bad, you couldn't show the Apple non-user-repleacable battery, and I thought you were paid not to show Apple in bad light... Never bite the hand that feeds you.

Simply Google for apple iphone battery troubles for more on that matter.

Back to topic:

OLED takes less power than conventional LCD screens (even IPS) due to the fact they do not require backlighting. Yet this new technology sports much better chrominance (color depth), luminance (brightness) and contrast ratio dynamic range (no leakage from polarizers since the LCD use backlighting usually always on).

Just like multicore CPUs are much more efficient and takes less power than single core, but that is another story...

Umm, he posted that picture because he could SHOW the battery (which makes it relevant to the discussion). Maybe you failed to read the post because he specifically railed on iPhone and its sealed battery.
battery in a smaller, lighter device, right? Also, I'll lay money right now that you've never bought a spare battery or swapped a battery on any phone you've ever owned.
@baggins_z
My previous phones (since 2000 anyway) all lasted for a week minimum so there was never any requirement for a spare battery.

To those who say 'turn everything off', what is the point of owning a smartphone? I may as well sell the iPhone, charge my old E65 and buy a galaxy tab or iPad.
@WinTard Alternatively one could also Google android battery troubles and the search would show far more results going further back.

Also one could Google Windows Phone 7 battery issues and come up with pages of results as well. Some of those gems are:

Just thought I would counter your obviously biased anti Apple slant.

At any rate there ARE solutions in place for this - from having extra chargers around (I keep a charger for my iPhone and my Galaxy S at my desk and plug in at lunch) to having a "jump pack" like the Richard Solo 1800 to using a Juice case. As Jason aptly said this is an industry wide issue.

I could live with a slightly larger phone if it meant that it would run for more than a day.

But batteries are a' changing. The world is a' changing.

While it is still a year away there is tech in the lab today that extends the capacity of existing Li batteries by a factor of 10. That would let you have all the bells and whistles turned on and still have a 40 hr life on the phone.

Move the tech to electric autos and the existing 70 mile range battery can be shrunk to half the batteries size/weight and still easily push the car 350 miles.

The world is changing and it will be wonderful.

MobileAdmin 16th Dec
Why are people shocked that their 4"+ screen with a plethora of data hungry Apps, tweets and emails runs out of juice? You also have ridiculously low prices for all the hardware you get so corners are cut and battery is top of that list to skimp out .. how else can they drive more profit by making you buy the extended battery.

One of the last good things about still using Blackberry is walking through the airport and not having to sit next to my iOS device that desperately needs juice. I swear sometimes it's like a whole little mob. Check it out next time you travel. $10 any available power outlet is being used by an Apple users.

I think the smart phone companies need to take a look at Nintendo. Those DS's run a pretty long time for gaming. I don't think I could play a game app as intensive as a DS game (like the new 3D games) for 6+ hours with out my phone dying on me. True mobile gaming: I think Nintendo beat them all :P

With all the technological advances we've made, there really isn't much reason for any of the smartphones and other mobile technologies to have the poor quality of battery life that we all put up with.

Either someone in the test lab is messing up continually, or the company doesn't really care about the consumer as much as they care about the shareholders. There's no way they can claim the didn't know about it. If they did, they would only look worse for not even QA'ing it in the first place.

They are giving consumers exactly what consumers want: Smallest form possible, big bright screen, lots of horsepower, all hardware on or on standby. If consumers demanded, as their top purchase priority, 16 hrs of "everything on" battery life and a month standby, and didn't care about size and weight, then the manufacturers would surely deliver it.

And here is where you have to seperate what Jason or you wants from what general consumers want. Let's face it, he is complaining about not having more than 4 hours of 4G use in a single charge like that shouldn't be enough. Forgetting that a few years ago someone who actually spent 4+ hours with his/her face stuck in a "cell phone" would have been considered by most to have a severe mental imbalance, or a teenager, now it's "almost" normal wink

To just how useful these devices are. They are used....a LOT. Maybe it just needs to do less. If they were not useful you could just shut off the data, notifications, bluetooth, wifi and such and then sit around crowing "My dumb smartphone lasted a whole week on a single charge doing nothing". Having enough power for "weeks" was a great selling point when the phone did nothing.

And you know what, as soon as they pop some new magic battery tech into these that makes them last days on a charge they very next phone model will be SMALLER and have its hardware jacked up to eat all that power and you'll be back to under one day.
Great post. I'm still not into this whole 4G thing 3G is good enough and battery lasts longer.
My old Blackberry Storm 2 battery lasted nearly 2 days with moderate use, mostly email and facebook. It was an OK phone unless you tried to surf the web - good luck with that. Maybe that was why the battery lasted so long, I gave up on surfing with it. I replaced that phone with the Droid Bionic the day it hit the streets, and I love it, 4G LTE at 10Mb, grin. Well, except for the battery life, I've discovered it could drain the original battery in 6 hours if I wasn't careful, and I needed to worry about whether the GPS, wireless, bluetooth, 4G, etc. was on. So I bought the extended battery pack that Jason mentions, which makes it bulkier and heaver, but much more useable. It will now last all day even with moderate 4G use. I'm OK with tradeoff, as the Bionic is a lot more capable than my old Blackberry. We want our smartphones to do so much, that we forget there is a battery life penalty for all that functionality. With the current state of the art, you need a big battery to make these smartphones useful. Maybe things will change in the future, but for now, if you want 4G surfing, navigation, email, facebook, ebooks, music, and all manner of other stuff on your phone, either get an extended battery, carry a charger, or go back to a "dumb phone". I'm just glad the Bionic has one of the biggest OEM extended batteries available right now.
Just give me a bigger battery that will last longer. If it's the Zack Morris phone battery, so be it. =)
FYI: In order to use the NFC capabilities of the Samsung-made Google Galaxy Nexus, users will have to use the original OEM battery that came in the box or buy one made by Samsung as third-party batteries would likely not work with the phone???s NFC feature. The reason being is that the NFC chip is wired into the battery, so only a Samsung-made battery at this time would work.
