Google: Android Battery Should Last All Day

- By - Source : Tom's Guide US

Google's CEO said that Android-based battery drainage stems from the transmit/receive circuit.

Some of us here at Tom's have noticed that our Android-based phones can munch away at the battery like a kid at an all-you-can-eat chocolate buffet. We're constantly having to run task managers to kill off leeching apps that insist on snaking resources in the background. The recent Twitter release is a prime candidate as well as Skype, Facebook, the MP3 Store, and even Google's Gesture Search.

Yet somehow Google co-founder Larry Page seems to think the Android batteries should last an entire day. In fact, if you don't get an entire day's worth of juice, then there's something seriously wrong. Page blamed apps as the source of the battery exhaustion and inadvertently pointed to consumers who let them soak up the juice.

Page recently made this observation at Google's annual partner forum (Google Zeitgeist) after someone in the audience asked him about whether Google was going to address the current battery issue. However Google CEO Eric Schmidt was quick to clarify Page's seemingly offensive approach to the question.

"The primary consumer of the battery life on these phones is the transmit/receive circuit," Schmidt said. "So tuning that and obviously figuring out a way to not use too much of that extends your battery life. And people bring in applications that are not particularly smart about that, which is what Larry is trying to get at."

While applications can be persistent in remaining in the background, other factors can eat the battery rather quickly. Some suggest that "cell standby" and "phone idle" are major culprits, however the Wi-Fi can also drain the battery if left on unneeded. The display is usually the #1 resource hog, especially if the device is in constant use.

I have a droid and it seems that it's hit or miss. Certain apps seem to take more battery and it always reports the screen as being the culprit. When I use advanced task manager the phone seems to stay in good battery health for the day.

Not sure if it's just by chance but it seems that the Google Finance app (stock ticker) seems to eat battery... Maybe it's communicating in the background? And the MP3 store always loads... don't know what's causing that to load in the background when I'm not doing a thing!

Not sure how accurate it is but you can go into Settings then to About Phone (at the bottom) then tap Battery Use to see detailed graphs of what's using battery.

I've got a Samsung Omnia II(Win Mo 6.5), and it has about 3 weeks of battery life with normal use(5-10calls/day, 2-3 games/day, and a webpage or two/day)



Hmm. Interesting. I might have to look into that. :)

Hmm. Well, time to make a comment that will quite obviously get rated down to at least -40 ( )But I don't have that problem with the only apple product I own.. My 3GS iPhone. I'm surprised if i HAVE to charge it more than once every 2 days.Just saying.Alright, now all you apple hateraids.. Fire away



How much do you use it? My friend has a 3G and it can last just over 2 hours if used constantly with games and web browsing, or if used just for texting and generally being conservative it lasts 2-3 days.

I'm sure some people will use there phone a tonne and will have to recharge often, while others could probably go a half week before recharging.

You will if you had os4 on it as multitasking will eat it up; why else do you think apple upgraded the iPhone HD battery?. Apple puts them in a hibernates state, but it's up to app coders to implement any of the new features. My 3gs goes quick and I broke in the battery just like all phones before and it still goes and needs a a charge every night and I'm not a heavy user.

I have an HTC Eric and can go 1-2 days with occasional use. Few calls, few checks of email and other crap is about all I do.

Troll harder please.

Assuming a very modest of 1 hour of active usage a day based on your describe activities, you're telling me your phone lasts 21 hours of active usage plus (3 weeks-21 hours) of idle time?

Get the f**k out.

I have a T-Mobile G1, My battery will not last a full day no matter what. If it is a lazy sunday and I hardly ever pick it up it still won't last all day. If I'm working and make 15-20 calls I am constantly charging it. It's a great phone but I was not expecting the battery issue coming from my blackberry that would last at least a few days. I still would not go back to the BB over the battery issue.

Really? My 3GS was dead before my 12 hour shift at work was over and that was moderate use of skyscape and a few calls and txt messages here and there. Maybe just my bad luck of the draw?

My HTC hero normally lasts 2 days with wifi off for most of the time, with little web browsing and gaming, with wifi on and playing some old school NES games i might get away with a full day.

My Hero is 1 to 3 days normal use. I do use taskiller after most things I do. If I use it a lot though, 1 day is the top with wifi usage and browsing and such.

I have a feeling the type of people complaining are the ones that don't understand -just- how little power that battery has when it comes to keeping a live data connection over a cellular radio for hours on end, screen and apps aside.

Toss in a juicehog screen and over 9000 background apps, and no phone will last very long.

It's a shame newer high-capacity battery technology isn't coming along quicker. Given the complexity of current devices and the ever-increasing complexity of future devices (LTE/Wimax, anyone?), a 1500mAh battery will get you from the home to the office.... aaaand that's about it.

Since I had my first Android phone (G1) battery life was a recurring issue. Manufacturers advise to turn off GPS, WiFi, reduce background mail sync frequency etc.

So basically they want me to buy their fancy smartphone and turn off all functions that make it stand above 10-yrs old phones. Great.

I generally fiddle with my Moto Droid almost all day, very few calls, however, it will go 1 to 2 days no problem.

if you download a good task manager program and kill ALL or most all of your apps you dont need my battery on my motodroid DOES last all day... barely, I'm at 10% before bed but it does.

One program I use which I love is called " Automatic Task Killer ". with automatic task killer you don't have to click and use the pesky task managers anymore, you simply select what apps to kill and every time your screen times out and goes black it automatically kills those apps for you.

My Droid lasts days if not used. It uses a LOT of battery if I use it constantly, playing games, etc.

My Palm Pixi lasts about 3-4 days between charges for normal use, heavy use is about 1-2. I've been pretty happy with it, it actually stays charged longer than my old basic LG flip phone.

Steve Jobs stated that Apple wasn’t the first to the multitasking party, but they would be the best. Although I personally don't use any mobile phones (of any description) I was certainly taken with the thought Apple have put into solving the problem with iPhone OS4 when I read about it.

With heavy use my Droid needs to be charged for a little bit sometime during the day, but for occasional use it lasts all day easily. When I rolled from 2.0 to 2.1 my battery life improved by quite a bit. The display is the real killer so when I'm playing games or using navigation it keeps the screen active for a long time requiring a mid day charge.

on my droid, if i'm constantly turning the screen on and off it seems to use the battery quicker than if i were just leaving the screen on for 5min at a time.

after about 12 hours (when i get home for the day) my battery is somewhere between 40-60%. I do email checking throughout the day and light web browsing for about 1 hour in total

"The primary consumer of the battery life on these phones is the transmit/receive circuit,"

Funny, on my Droid under battery use the screen takes up 45-50% far more than the 13% from the transmit/recieve functions, soooo doesn't really matter what apps I use the damn screen set to lowest brightness uses far more power than anything else. I wouldn't give up android for anything else, but don't blow smoke up my ass about the damn battery.

I have a HTC Tattoo running Android 1.6 Donut - battery lasts 2-3 days, with me writing around 20 messages/e-mails a day, talking 10-20 minutes per day and surfing the web 15 minutes per day.

Sooooo....I'm kinda satisfied :)

Droid user here, my battery easily last all day, 13 hours later and it is still at 50-60 percent battery.

Best thing to do is long click one of the three screens and add the power widget. This alone will help you turn off wifi when not needed, turn the brightness to 50 percent, turn GPS off when not used, which will hog the power just as quick as the screen at full brightness, syncing which I keep on all day long, and bluetooth off when not driving.

I have found GPS is the main culprit of battery usage with screen set to full brightness as the second. You can always see what is eating the battery under Menu->Settings->About phone->Battery use

I do have a task killer program that I only run once every month or so, and I never turn my phone off setting at 1,130 hours uptime with no issues, Droid does!

gwolfman :
That's because the iPhone doesn't multitask!



You don't give apple enough credit. Even though they don't have multi tasking yet, when they do put it on the iphone, it will have a better implementation than anything out there yet. If I had to guess.. It will most certainly not have to deal with some stone-age "app killer" program to deal with battery destroying programs. It will probably feature some sort of alternative "sandbox" where the program will sit until called upon. True, it'll be slightly slower than those phones that hold programs fully ACTIVE in RAM, but lets face it.. while I'm guessing that will be apple's intent, it will still be up to programmers to utilize such a feature.. Which is probably what is taking apple so long.

As I said, thats MY guess, and I'm certainly no expert.

My cliq needs a charge every 36 hours, great battery life. On weekends with heavier usage I still get a good 18-24 hours out of it--much better than my old sidekick.
