Ok I have been reading since literally the first day the G2x came out about the "Horrible" battery life of the phone. So, after toying with it for about 8 days I have nailed it down so that the phone gets about 20 hours of Moderate use(Constant texting, internet for emails, YouTube, and searches, and probably about 2 hours of light gaming(not Nova or NFS)). So, Outside of the obvious like make sure your bluetooth, wifi, and GPS are off and turn your display brightness down here are my steps to Better Battery Life.
First - Root The Phone. There is plenty of links and help if you don't know how or have questions about rooting.
Second -(Root Needed) Use Titanium Backup or Antek App Manager(Antek is free) and Freeze or uninstall all the bloatware that you don't use off of your phone. Especially Car Home cause along with people on XDA i have also noticed that it does use a fair amount of battery for NO Reason.(Be careful with My T-mobile and My Device might throw your phone into a force close frenzy)
--For some reason people have been asking exactly what T-Mobile Apps you can freeze/uninstall and the answer is. All of Them. I personally left My T-Mobile(To view Minute Usage) and Wifi Calling(Cause I have no service in some buildings) and froze the rest, but you can get rid of everything you don't want or use.
Third -(Root Needed) Set CPU. Have had this on my G1 and N1 and it does nothing but save battery. I currently have it set on 216 - 1000 for when the screen is on and the only profile i have is for when the screen is off and it is at 216-216.
(Alternative) Pimp My CPU. I now am using this for my G2x because I am running custom kernal. Personally I like Set CPU better, but do to the fact that Set CPU can't get past 1000 MHz makes it kinda useless for the G2x Tegra 2.
Fourth -(Root Needed) Battery Calibration. There is an App in the Market for this and it is easier and less of a hassle than Factory Reseting the phone. Just charge all the way to 100% and i discharged to 0% and recharged it and Amazing difference in battery life. (And don't doubt the Calibrator cause right after i set it to calibrate the initial 100% got to zero in about 7 hours, but after that one cycle i was getting the 20 hours i am now)
Fifth - Elixir. Not only does this app display anything you might wanna see about your phone (CPU usage, battery temp, battery percentage, memory...) it also has a widget that lets you toggle your internet on/off. Which is almost necessary since "4G" kills battery like no other.
Sixth - Auto Sync. I shouldn't have to put this, but if you don't know your phone is set up to auto sync all your Google apps(Calendar, Gmail, Contacts) and Social Network apps(Facebook,Twitter). So go into settings and make sure that you turn auto sync off.
Now the next steps aren't proven to give extra life, but i did them just in case and well I get 20 hours of use like i said before.
Sixth - Watchdog. This app monitors all the other apps and processes in your phone and will alert you if a rogue app is draining your better life.
Seventh - I did the "Alternate Battery Fix". This involves changing one setting and who knows maybe it does help me get extra juice.
Link: http://forum.xda-developers.com/showthread.php?t=1051036
Eighth - Wifi Never sleep. Supposedly according to some if you change wifi to Never Sleep it will stop some loop in the programing which in turn will save battery.
Ninth - Wifi Calling. If you didn't decide to freeze/uninstall this app. Make sure that this is OFF, because whenever you have wifi on it will constantly flip between Wifi Calling and normal radio towers, which once again is bad for your battery life.
Well, Thats that and if y'all can think of anything that i missed or have any questions or ideas let me know! And remember this is a Dual-Core, High-End, Monster Phone and duh if you use it hardcore (Movies, HD Games, tons of web browsing) the battery will die fairly quick.
P.S. Will post a Screen Shot of Uptime for 20 hours later(if it doesn't Re-boot before i get to 20)
Update #1: Have read all the posts and have decided to speak up about a couple things.
Task Killers - I feel like these are brought up in every thread ever created about batteries, and well they are useless. So, if you are gonna bring up the ram usage argument. Android is made to kill programs that are either inactive for to long or the operating system will shut down background tasks if a new app needs the cpu power. Than for those who say that it helps close programs and makes the battery last longer.Having a Task Killer that basically re-closes the same apps over and over again(These are usually bloatware background apps that for some reason never stop running) is not gonna do anything except waste precious battery life on running the task killer itself cause the app will just restart. Your best bet is to run watchdog find the apps that are taking to much battery and freeze/uninstall them.
Managing Apps - Apps like Tasker, Juice Defender, and the like are in my opinion not battery savers at all. They are just tools to implement what i have already previously stated, but that doesn't mean that they aren't useful. They are good if you have a busy schedule and have to constantly turn the internet on and off or switch between certain settings, but they are not actually a cause of better battery just a tool to implement what you could do on your own.
I've done most of those things over the course of the last week and I just got a little over 24 hours on my last charge.
Those tips are legit.
Thanks! I was kinda worried about it cause it was my first post!

Great job! I've been getting about 20hrs of battery life using some of these... now I have more tricks to add =-)
Good job! I'm almost done withall the tweaks and have say it helping. Thanks

Great tips. I was doing most of those, but have added the calibration software as well as watchdog. I have also found Juice Defender to be a big help.
Thanks again.
this is still not acceptable for a phone in 2011 to still have that kind of battery, most people out there aren't really concerned about tweaking their phones or dont even know about it. Im not gonna use setCPU or anything else, i expect things just to work flawlessly out of the box.
Tasker can be a friend in this whole deal too.
If you can automate your radios & screen brightness to exactly what you need when you need it you can save significant battery life.
If your WiFi calling app can't stay on wifi, you need to fix your wifi network and not your phone.

With all of these changes having a toggle for haptic feedback I assume would help a ton...considering its a touchscreen and a retardedly fast phone. Otherwise it vibrates on every damn user input. Just curious what others think about this. Anyways, thanks for this post....the forum is getting congested.

Yeah, but on the flip side your an early adopter for technology that literally JUST CAME OUT and so there is no perfected system for it. I mean the version of android we are running right now doesn't even truly support dual-core! So yes this is the price we pay, and if dual core had been out for two years I would completely agree but it hasn't. This is what android has always been built on a semi flawed system but top of the line technology and thanks to the great community we have we can push the limit of every device out there even the g1.

I meant this for people like myself who live in an area ( or college like me) where you are constantly moving in and out of wifi range and that would take a drain on your battery.

I think the reason we have so much haptic feedback though is because we are lacking physical buttons and the small vibration gives us the sense of a solid keyboard even though as you stated everything is a touch screen. Well that is my 2 cents anyway.

I will definitely look into tasker and check it out personally and add it to the list later! Thanks!
Update: I have seen programs or apps like this before many moons ago i used a program called wisyncplus and basically it is just profiles. This I guess could be used to increase battery life, but in my opinion apps like this and Juice Defender and what not are simply 1) too much of a hassle - cause you have to usually set up each profile individually 2)This is more of a convenience - It doesn't actually increase battery life it is just a manager almost like a widget.
Than back to your argument about the screen brightness my auto-adjust does just fine depending on the lighting and honestly in less your watching a movie, playing video games, or doing intense web browsing your more than likely not even gonna have your screen on that long. (and to those of you that say the Auto-Adjust doesn't work remember that this is an LCD screen it is lit from behind so it is gonna seem brighter unlike the Nexus S which is lit in the screen making it viewable with less brightness)
Than for automating radios honestly there is already widgets for that. The stock rom comes with a Wifi on/off widget so no complaints there, and elixir(which is a free and very useful app) comes with a apn off/on widget which is really all you need cause in my experience unless my internet is on I see no difference in battery life being GSM preferred over WCDMA preferred.
So in less you really do have a tight schedule, or just don't wanna mess with changing settings manually(and with widgets), Yes, Tasker is perfect cause it basically does everything for you.(even though i am pretty sure there are free apps exactly like Tasker)
(Sorry if this came off kinda rude I don't mean to flame at all just trying to say all of my opinion and back it up as best i can)

if this is the case, i don't think that an open-source phone is for you. the beauty of android is that anyone can personalize it and tinker with it.
the g2x is sort of like a muscle car- it has lots of [dual core]power, but the trade off is trying to manage battery life.

For the sake of min/maxing battery drain I would think toggling the vibrate after every input would help. I actually like the keyboard without it pulsing all the damn time. And my hearing might be a little sensitive to where I dislike the fart sounding vibrate motor. Haha.

Couldn't have said it better myself. This is exactly why I am a huge android supporter/early adopter, a car fanatic, and a Mechanical Engineering major. Because I love the individuality of it all and to be able to own something that can be unique to me.

I dont think turning off haptic feedback will really make to much of a difference in terms of battery use.
Our phones are dual core phones, in every test run dual core phones have less of a battery draw because two cpus is better then one. When dealing with a multicore phone/computer the device can have more power without using more energy because there is less stress on the cores. The old way was a bigger battery drainer then this because 1 core would have to use more energy to produce equal amount of power that a 2 core setup would. As spencer said and we have all been saying its more of a software issue then a hardware issue. Imagine loading a computer with 24gbs of memory and have an core i7-Xtream chipset and using windows 7 32bit its pretty much a waste. I believe a lot of the issues that everyone is experiencing will be fixed by a software update or the dev team when roms of the gingerbread nature come out.
Spencer nice post btw!
Hi
Have had this phone for just a day.
Been struggling to make up my mind whether I want to get it because of the limited memory.
But finally decided to go ahead because it has good reviews on its performance and battery life.
No complain about the performance, but the battery life?....
Played Tripple Town for just about one hour and 30 mins and the battery goes down from 66% to 35%, the majority of which is comsumed by the screen.
So here is where I am. 5 h 47 m on batter, 32% left, 69% of the power drain is because of the god damned screen.
Seriously HTC, how can you manage to get so screwed up with such a decent processor.
you get rid of the removable battery, ok, nowadays the battery lasts reasonably long.
you get rid of the Micro SD card and force us to use the rubbish dropbox. 50GB 1 Yr cost $99. Why don't spend that money to get us a decent bigger memory? But ok I want the performance, I am willing to give up a bit of space for that.
But Finally SUPER AMOLED. Seriously, what kind of dump decision is this to fit a more-than-a-year old technology to such a decent new processor?? when we know all the bad thing about this screen.
It alone kills all the power efficiency the 28nm processor can offer us.
So now this phone's battery cannot out perform (when you are actually using it) neither of my previous phones: Dell Streak and Atrix. Don't tell me I have to compare the battery life by switching off the screen and just let them sit there.
I am very disappointed. very disappointed.
This will be the last phone I buy from HTC.
It sounds like you don't know about how to manage phones.
You prob was running lots of applications at once and brightness all the way up it still won't go from 66% to 35% sounds like a bad unit you have.
no... the brightness is at it's lowest level.
I use anrdoid assistant to kill process once an hour.
There is very unlikely this is a bad unit. Nowadays these manufacturers control the production quality very good that the chance I get a bad unit is probably as low as winning some lotto.
For starters, your device is BRAND NEW so battery will take about a week or so to break it in, just be patient. Also, killing tasks will only end up using more resources since Android will most likely just start them back up once it gets the chance. Run your battery down the first couple of days and charge it overnight and you will start to notice it getting much better.

Kill Process runs only once an hour. So during the time I was playing, it probably just ran once. I doubt it will cost much power at all.
I understand it needs time for the battery to warm up. But even with that taken into account. it is not looking good. It reminds me the suffer that Desire caused my friend.
Hopefully this doesn't turn into a bigger issue; keep us posted!

sorry mate but this is just stupid. first of all the battery meter is not calibrated in a new phone meaning the reported battery state is not accurate. you have at least to charge the phone once to 100% and discharge it fully to calibrate the 2 extrem states. before that everything displayed is just a rough approximation. at the first discharge i had ~20% left and the phone was down to 0 in just some minutes of heavy use. after 2 cycles i get ~-10% for an hour of heavy use. so stop crying and give the phone some day's to adjust

Well I hope jodue is right: the battery needs time to fix itself.
I will give it a week to see whether things will improve. If not I will go to store to get a new one.
I have been using Android Assistant for my Streak and Atrix. It turned out to be just alright.
Anyway I will remove it and see how it goes.
Ppl have wrong idea that AMOLED is more power efficient. I remember reading a review some time ago on battery life of smart phones. It tested a number of phones and the outcome is that actually on average the AMOLED (at that time there wasn't SUPER AMOLED yet) devices last less than others.
But anyway...

This is the most stupid thing one can do. The processes will likely be restarted by the OS and you consume more power than you would have consumed by letting android do his things as designed.
Google itself suggests not to do it. Even the most honest task manager apps suggest not to do it. (e.g., http://android.nextapp.com/site/systempanel/doc/autokill ).
Anyway, before judging battery life wait few days. I own a One X, and battery life improved suddenly after few recharging cycles. ;-)
About the display. I readed somewhere in this or X forum, that:
1. LCD does consume less power, but for X version, since its bigger screen, it takes more
2. AMOLED screen power consume depends on what it have to display (colors). Black/dark colors need less power to be shown while white takes the most power...
You get 25GB free on dropbox with all one series phones plus a further 25 per referal

This. Many people don't know/forget about this. Using a dark theme on apps you use most on an AMOLED phone can save a lot of juice, much more than all those stupid Juice Defender/task killer/manager apps can ever hope to.

You cannot ask all the website to go dark background can you?
Ppl use the phone to do different things. Games, Browing internet... thats the whole point, the phone should perform consistantly for all tasks, not just looking at dark home screen. HTC hasn't even figure this out yet??

in browser-setting you can invert white background/black background
no battery issues here
No battery issues, with slightly higher than average use (downloading loads of apps, playing some games, using google maps and a half hour driving nav and some music lsitening) over the first few days I've averaged 24-36 hours which I'm pretty happy with.
There are a few software things I don't like though
First, I miss having settings in the notification tray, it's one less tap of the screen. Also, the tweaked recent apps list seems pointless, you have to flick from one to another... the Stock android 4 recent apps scroll is much better, it let's you see/do more with less interaction. I also noticed a bug where the wireless signal will appear as null in the notification bar but if you view the the details in settings it says that the wireless signal strength is excellent!
Don't let any of this put you off though it really is a great phone and feels great in the hand... CM9 may rescue all!
Have the One S now, arrived a short while ago. The most annoying thing is that a stock device only has 9GB of that 16GB free when you get it.
This is nuts, I will not be using dropbox, there are many nefarious reasons why HTC want people to use dropbox or any cloud storage, this does not work well while I am roaming folks. This is not good for a business phone, I maybe sticking with my DesireHD.
Its sad, that many ppl who consider themselves technophiles do not even understand the battery of their devices.
ANY device with a modern battery should be initially charged overnight or 7-8hrs at least even of the little green light tells you it is all OK after 4 hrs. Do that, and give it a week to break in and I assume there won't be anything to complain about anymore.
Somy link to a decent site discussing these battery care tips and characteristics should be auto-pinned to each new device subforum cause the first complaints are ALWAYS about the battery life it seems...
Just to give some quick history: I'm a power user, but I'm not a programmer, so my knowledge is limited to what I've experienced and not what the XDA community experts would be capable of doing. I've used RIM, Apple, Android, Win Phone, OSX, DOS, Windows from the beginning, and currently Win8 on my PC's.
Android is an excellent platform, but it has one major flaw: Why does it need to use battery when it's supposed to be sleeping?
I could never go back to Apple. It's far too locked down. It's just.. ugly and clumsy. I loved my BB Bold as a phone, and was saddened to see them go the way of the dodo. I use a Windows phone now, because the battery life is well maintained due to it being somewhat locked down, but not to the point of Apple.
Here's what I'm suggesting for Android. This is primarily for tablet users, but could apply to consumer phones as well.
1. There needs to be a way to force a true sleep mode. This should lock down apps, widgets, and all non-essentials. There is no reason you should have to turn a tablet off every time, or check wakelocks, to minimize battery use, if you put it into sleep mode. If it could boot in the time my ultrabook running Win8 does, I wouldn't care. I'd just shut it down fully, and turn it on for a boot in under 8 seconds. They cannot. Neither can the competition. There needs to be a true sleep mode, and a semi-sleep mode, and a completely on state. One should be for, well, when you're asleep or don't care about updates. One should be for background updates working, but not taxing the battery heavily. One should be for full on status and doing all of the great things Android is capable of.
2. Tasker is pretty neat for some things. JuiceDefender is pretty neat for some things. Unfortunately, they don't solve issue #1. There needs to be an app (root required I'm sure), that truly takes over the combination and applies a full lock-down of all apps and data with the press of a button.
3. It would be nice to have a method to do these things for the average person. The Kindle Fire is pretty locked down, but still Android based. It also gets good battery life because it doesn't have as much running in the background when it's not being used. There is no reason why there shouldn't be a way to switch all Android devices to a mode like that, on the fly. Basically, if you want a widget heavy homepage, but don't need them doing anything when you click a sleep button (like on a laptop), why not have it do exactly that. This way new people can have all of the fancy widgets they want, but also not have to power down when the tablet or phone is not being used for anything but phone/text/email-sync use.
4. People won't want this to be something where screen off means no data, or updates. People will want this to be integrated into a quick button push that is easily seen as having been toggled. "Why you no go sleep like laptop?". There is no reason that my Nexus 7 should use more battery power in its "sleep" state, than my Lenovo i7 tablet ultrabook running Windows 8 does, while sleeping. One could last a few days, one could go for a month.
/end rant... I love my Nexus 7, and loved my Droid X, but my Win phone gets amazing battery life when I'm not using it, because it basically does exactly what I've explained (for better or worse). Ipads are similar. The Blackberry Bold was also similar for me (essentially locked down to phone/email when not in use). The Kindle Fire essentially does this to some extent. The iphone... well, that just stunk all around, so that was the only device I really did not like at all (bad battery life, and locked down anyways). Don't get me wrong, the Nexus 7 has great battery life when in use, and after tinkering, but why the need to shut it completely off at night when it should only use about 1% of the battery in a sleep mode during that time, and not 15%?
I have a rooted Kindle Fire running the latest power saving kernal update for CM10 and it can sleep all night with only a 1% decrease in battery life. I understand the point your trying to get across. Maybe in time we'll see some software development that will do exactly what you were saying. Shutting down the device completely is very effective in conserving battery life (especially if you are running many apps and services simultaneously) but also helps the system to run smoothly.

Ipads are similar. The Blackberry Bold was also similar for me (essentially locked down to phone/email when not in use). The Kindle Fire essentially does this to some extent. The iphone... well, that just stunk all around, so that was the only device I really did not like at all (bad battery life, and locked down anyways). Don't get me wrong, the Nexus 7 has great battery life when in use, and after tinkering, but why the need to shut it completely off at night when it should only use about 1% of the battery in a sleep mode during that time, and not 15%?

Yes i appreciate you advice but why mobile company cannot make more powerful battery backup for android phone.

1. There needs to be a way to force a true sleep mode. This should lock down apps, widgets, and all non-essentials. There is no reason you should have to turn a tablet off every time, or check wakelocks, to minimize battery use, if you put it into sleep mode. If it could boot in the time my ultrabook running Win8 does, I wouldn't care. I'd just shut it down fully, and turn it on for a boot in under 8 seconds. They cannot. Neither can the competition. There needs to be a true sleep mode, and a semi-sleep mode, and a completely on state. One should be for, well, when you're asleep or don't care about updates. One should be for background updates working, but not taxing the battery heavily. One should be for full on status and doing all of the great things Android is capable of.

Deep Sleep Battery Saver, im using it and works great.
How are you supposed to get notif0fications, texts, email?

There will be lots of wireless power options so you will simply put your phone or tablet for the night and take it back fully charged in the morning..
To my experience the most power consuming part is the bright nice display that eats most of the battery. Waiting for better display technologis.
Thinking a out Windows phone as well.. good idea?

It would be a practical option for tablets, where a sleep function like laptop computers use could be implemented. But even in sleep mode laptops still use power keeping data in the RAM and monitoring input devices for user input. I'm not sure how much power you would save on an Android tablet with an actual sleep mode. The moving parts in a laptop (HDD, fans) shut off during sleep so its power savings are more significant that a completely solid state tablet. IIRC even my laptop uses more than a percent of battery life if I let it sleep on battery overnight and it has a much higher capacity battery than any tablet.
On phones you need the device to be awake to receive texts, calls, etc. Since its constantly connected to a cellular network there is going to power used keeping the connection established. My Droid 3 actually has a sleep mode which is essentially airplane mode plus sleep, I've never tested how well it does with the battery as its my primary phone for now.
Hi,
I was wondering how was the battery of the Microsoft Surface Pro? I currently have the Surface RT which I find really amazing but I have an occasion to switch to Pro, should I ? The only thing that keep me against switching is the battery life.
So..
- How long can a Microsoft Surface Pro stay in sleep mode before the battery gets empty?
- How long can it handle the screen ON at 'Auto Brightness'
- How long can you use the device with normal use ? (Browsing, Facebook, etc..)
- How long can you play basic game (ie Chess, Minesweeper, etc..)
- How long can you play hard game (ie Fruit Ninja, Angry Bird, Call of Duty)
Huge thanks for those who will answer and please no lie, I want the real time
3-6 hours of use dependant on scenario.
What you use it for and what others use it for will be different so any answers you get should only be taken as a ball park, same with phone batteries, the number of users I've seen over the years say they can only get half a day of use vs others that charge every other day..
The battery is poor at best... I hope they implement the 'new' battery into our tech soon.
Alright and how long can it stay on in sleep ?
If I use a power saving profile with low brightness and CPU throttled to 50%, I can get between 5 and 6 hours if just using Word, Excel and web. That is with a BT mouse and Type cover.
If I don't throttle the CPU and use the pen a lot (eg. marking up a pdf, using one note, or using the pen instead of a mouse in tablet mode), then the battery can last less than 3 hours. The pen seems to use a lot more power than just typing or using capacitive touch.

Hmm weird that the pen seems to take a lot of battery, the best would be that you compare with the test with the CPU locked Probably gonna exchange my RT by tomorow or so
The pen uses more power regardless of the power setting.
I also notice that it gets hotter if using the pen a lot, than if not using the pen.
It seems that the pen requires more cpu power than just using a BT mouse, hence the higher heat and power drain.
Battery life is just like any other ultrabook with a 42Whr battery. When I disable Turbo and use 'Power Saver' profile for less a less aggressive SpeedStep, under my usual mixed Internet browsing, penning OneNote, and annotating PDFs I get 5-5.5hrs of usage.
Use it like an ultrabook, treat it like an ultrabook. The content consuming tablet side of it is just a nice bonus. It received it's "Pro" moniker for a good reason, not for you to d*ck around wasting time. You want to do that? Go pick up a Surface RT, Android tablet instead.

I have the Microsoft Surface RT, I'm thinking to return it for the pro
Hi sleep mode lasts at least 10 hours. Probably much longer though as I have not been able to leave it alone longer than that. But if I have a full charge and set it alone over night. I wake up with almost a full charge (8 to 10 hours)
Oh, it'll last many times 10 hours. Sleep mode on laptops from 2000 - machines that got 2.5 hours on battery if you were lucky - could frequently hit a week if fully charged. My Core i7 work laptop (5 hours battery life in typical usage) will lose less than 10% of its battery life / day of sleep mode. Surface Pro has a smaller battery, but may also use more efficient RAM modules/connections (keeping RAM alive is pretty much the only significant drain for a sleeping PC) and should still last at least a week.
Thanks for all the replies ! I finally switched Let's see how it goes
This gadgethacks article from two years ago suggests limiting battery charge to 80% and even links to an app to do so.
Given the speed at which things evolve in the Android world, is this still a good idea today, and specifically on OP7 devices?
There is much debate around this but I personally stop at 90% and try to recharge around 15%, not letting it go lower.
Thank you! It's helpful to hear the latest thinking on this.
Forgot to ask: do you control that manually, or do you use something like this root app?
Taking it out for a spin but not sure what to expect.
When phone charges 100%. It's not using maximum capacity. Neither is it fully discharged when it hits 0. Manufacturers of course know that and that's something they take into account calibrating the software. I see no reason for limiting it further lower and making yourself to charge it more frequently. That wears it out faster instead
Help!
How can I run?

I use what is shown in the attached screenshot.
Thank you very much.
For anyone else following the thread, looks like this module is referred on this how-to guide and this official thread.
I'm a ~20 - 90% kinda routine. But I don't dwell on it...
If you use a Chargie device (https://chargie.org), you can limit the charging of any non-rooted phone. It's a much better option. And it's also developed and tested on a OnePlus 7T, so it works well with OnePluses. Check it out.

ACC
I'm using ACC by VR25 since years on a Redmi Note 4 and now on my Pro 7. You may find it on XDA and Github. It's a Magisk module and you need root rights. Configuration is done by command line, but default is max. 80% and starts reloading at 70%. There is also a gui available from Matte Carrara called AccA, which I never used. I can recommend ACC, it's slim and works rock hard.
