Battery life VASTLY improved since update

unplugged 2 hours, wifi on, gps on, auto update on, facebook, played friut ninja for about 20 minutes, 1 game of cribbage, and been getting 4-5 email per hour, battery at 86%, before I would have been at 60% with that much use.
Anyone else seen battery life increases?

This. It's noon and I'm still at 80%. I used to have to set my phone to flight mode all day at work just to make it through the day. Now I can leave 3G on all day and not worry about it. That's the best part of the update in my opinion.

I was about to post this also. Yes, I have noticed a dramatic increase in battery life since I've updated. Now granted, it's been less than 24 hours but it is noticeable. I'll see how it goes over the next few days. But I agree, I am very happy with the update so far.

Which ROM we're you guys running before? FJ6 (stock)? A lot of users noticed better battery life after updating to some of the leaked builds (JH2 onwards)

I'm running completely stock-out-of-the-box since I got it.

I actually have worse battery life since updating. Have background sync off,GPS off,push off and lost 30% from full charge in 2 hours

I have noticed the same with all of the same settings as you

4h 45min since unplug.
Email push multiple times an hour, text messages, light internet use, light market use and 35 minutes of guns'n'glory. I am at 71%

Glad someone else noticed this
I'm a victim of the partial update but my battery drain has been nearly half! I've actually left live wallpapers on and can make it through the while day at the rate I'm going

6 hours 53 minutes since unplug and I'm at 23% battery. This is roughly on track with previous battery depletion, but today I've been doing heavier internet and Facebook use than usual. I think that, previous to this update, I would have had to charge by now. This is with background data and sync on, over wifi, with a combination of Google Listen, Music Player, and Pandora use.
The telling point is that screen battery use is about 10-12% lower than usual for this type of usage, at 54%. I've seen it as high as 70% on days when I'm playing around with the phone a lot.
I'm ready to call this an improvement.

My phone was at about 75% at around 8:00PM last night. It's currently 2:42PM now and it's only down to 25%. Granted, it was in sleep mode from around 12:30AM to about 7:00AM. But I did use it moderately last night and throughout the day today. So the battery performance has definitely improved for mine (stock with yesterday's update).

For those who have seen an improvement:
- Did you use a task killer pre-update?
- Are you using one now?

Same here... I also let the phone drain to the point of where it shut off, charged and lost 30% in 4 hours!

Yes

Unfortunately my battery life has been greatly decreased by the update. My phone is rooted, but the update installed without any trouble on the first try. Before the update the phone was fine between 9am and 1-2am without charging it at all. That's being on wifi most of the time, and maybe a bit of talking, e-mail, and rss reading. Once asleep I'd let it charge overnight. Typically Display used the most battery, usually about 50%.
Since the update I find that I need to charge the phone in the middle of the day. The first full day of the update I used the audio player for several hours, so I thought maybe that was it, but I've done that before without a major impact on the battery. Today I didn't use the audio player at all, and after 8 hours the battery is down to 26%.
According to the power usage information the largest consumer is Voice calls, at 29%. That was 11m 46s of call time. Looking at Juiceplotter, for a typical day at work before the update my battery dropped about 2% in 2 hours, with the phone on wifi, and otherwise idle. Today the phone lost 6-9% in 2 hours of being idle.

The last time I charged my phone was yesterday morning. I just plugged it in an hour ago at 15%. Thats like, 35 hours on a charge after moderate usage. Not bad. Much better than my old G1 heh.

I'm at 45 hours, still at 29%. Light usage, probably ~12 hrs in flight mode, but music player on for about 5 hrs, 5 min voice call, a few texts, some facebook/web. Still very impressive!

I've had slightly better battery life since the update.

[Q] What is "normal" battery life?

I switched from an old WinMo 6.5 (Verizon Imagio) to G2x. Absolutely love it, except the battery life (there is backlight bleed too, but not too annoying).
But when I read thread here, seems my battery life is kind of okay?
1) Went to sleep at 1:20am. Phone had Gmail sync, Exchange sync every 15 minutes, News & Weather widget, and ScoreMobile widget. Checked battery at 5:40am, it was down 11%. So roughly 10% battery every 4 hours. This means 40 hours battery life if I leave the phone idle.
2) Today I wanted to drain the battery then give it a full charge. So I factory reset device twice (each time it automatically downloaded all 28 apps I installed before). A 1 minute phone call. About 1 hour web browsing. 10 minute Goolge Maps Navigation. Tweeked settings of my favorate text reader and read a novel for about 2 hours. Then watched YouTube for 30 minutes. Other time, phone was left in my pocket. Battery lasted about 11 hours.
So, is it normal battery life for G2x? With CM7, is it possible I can extend the battery life to 16 hours in scenario 2?
I think it is NOT normal battery life because when reading the novel (screen brightness at 20%), I can see 1% battery drop every 3 minutes!!! The text reader just displays static text until I flip page. My reading speed is about 2 pages/minute.
Compared to my WM 6.5 device, I barely notice any battery drain when using the same text reader app (WM version of course), same book and same reading speed.

Well people have found that the only issue with android really is the damn battery! some live through it, some buy extended batteries (like myself) and others just don't feel it since they are used to charging regularly. When compared to winmo 6.5 android is just doing so much more in the background comparitively even though winmo 6's multitasking is pretty neat. I guess other thigns to consider would be your screen resolution and that damn 14.whatever hsdpa chip you got in there!
Btw if you are using a app killer, i suggest try taking it off and see if you feel any diffrence.. i did.. i just found out the rogue app and said good bye to task killers and my battery was a little bit more promising then since it was on an aggressive kill certain app more earlier.
One thing though if you were to put the phone on a stanby time you will notice that it could really last but when doing something you can as you said practically seen it burn fuel, I guess the advancements in tech/screens/etc are just way beyond todays batteries!
I found my stock 2.1 doing much much MUCH better than CM7 or 6 even though people say Cyanogen was doing much better on some phones in terms of battery.

Can somebody post the battery life of their Vibrator compared to this phone?
I'm so mad, U mad?

I had mine off charger for maybe a total of 15mins cause I was deleting stuffoff the sdcard and battery was full it dropped 3% within 15mins
I had my myt4g with miui rom idle with wifi on for awhile yesterday and it didn't drop a % until I used it but even then it still hardly was draining. This LG drains way to fast!!

The battery life WILL improve over the first few charges. My Nexus S was TERRIBLE when I got it. 8-10 hours max. After 2 weeks or so, I was getting 25-30 hours of moderate usage.
The G2x I got ~ 14 hours of usage right out of the gate. I'm on full charge cycle 3 or 4 now, and I'm already over 19 hours. Hoping I can end up at around 25 hours or so.
The batteries AND the OS need time to 'learn' each other. The batteries need to break in as well with a full COMPLETE charge cycles. IE charge too 100% and use it until it dies, then charge fully. It also helps to leave it on the charger for about 8 hours PAST it hitting 100% the first time for some reason.

[Q] Actual battery life

Hi guys, any thoughts regarding Battery life? I get roughly 8 hrs, not the 9.5-10hrs advertised/reported in the forums. Of course, this is with very high use, screen on 7.5hrs, wifi on the whole time, plex on for an hour or so, mobo video playing for an hour, and web browsing for a couple of hours, and some games too. Is this standard? Dock battery is ok, gives around 5 hrs. Any ideas on improving battery? Screen stays at 60% brightness all the time. Plus i have cnn, facebook, youtube, pulse, cnbc and plume widgets on. And active mail sync in the background.

The 9.5h time is stated for constant 720p playback so I don't think your usage is that much higher. I never stopped the time for my ASUS but I am happy with it and I guess that's what matters most.
I use SetCPU (requires root) to set the clock speed to 216MHz when idle. That seems to improve battery life.

I am not getting anywhere close to 9 hours. At first I thought it's the apps I have been running in the background or the brightness, but it's the same after I adjust it. I get about 6 hours.

Dude....6 hours is pretty low.anyways, i havent rooted it yet because of the impending otas.will do it as soon as a gr8 custom rom comes out.

Yes but i do video streaming over wifi. Also my wifi is on the whole time. And as far as i know, wifi takes more battery than video decoding.

The 9.5 hours is for
Airplane mode
playing a local movie, only
display at about 30% based on the NITS listed and Anandtech measured brightness
I bet you can achieve the same if you duplicate their testing scenario.
As for improving battery life decreasing screen brightness can have a huge difference. The screen is often the #1 power usage item when I check on my phone. Also, reduce the checking frequency of any task that needs Wifi to get data.

It's been 15 days now since I had the TF and I can tell you based on my usage - I used up;
12% per hour - airplane mode, play games watch movies in auto brightness
1% per 2.5 hours standby.
So more or less 9 hours usage should be achievable.

I get about 18 hours of constant use with dock

I play with the thing all the time and I honestly haven't ended a day with my battery being below 50% yet.
Actually, out of fairly constant use, I haven't charged mine for, let's see... 2 days, 6 hours, and 52 minutes. Currently at 48% charge.
EDIT: Oh, and I don't have the dock, so it's not counting that.

It stays on auto. When it lasts me multiple days, I can't say I really worry about saving battery much.
For example, I unplugged it this morning at 7, played with it quite a bit today including playing Zenonia for a little over an hour and letting my friends play around, and my battery is currently at 75%.

Hi all. I just wanted to chime in on this thread here. Im a former owner of a xoom and can say that tablet was a beast when it came to battery life. I could have a full charge last for 2 weeks+ with very minimal use all consumed by idle standby. That was something to be said. The tf isn't as good; I can tell already, but I was surprised today! I charged it overnight and unplugged it around 11am. 98%, until I woke it up right now! Its at 97% with 13 hrs 39min. I probably had the screen on for only 5 minutes, but pretty good! One thing to point out that helped me a lot was to always have the tab in airplane mode. You can still have the wifi on and stay in airplane mode. That seemed to make a difference with the xoom. Just my $.02

I get 5ma constant use in sleep mode. By that logic, u would lose 1% in 13 hours on sleep mode. So yeah, idle use is pretty good. Decent tested flight mode yet though.but seriously, y doesn't battery use show the percent divisions like my phone? :O

Its doesn't seem that any of you guys are reading the manual when it comes to battery.
It says it clear in the manual. Why not follow what the book says, I guess some dont read.​
"If you intend to use battery power, be sure to fully charge your battery pack before going on long trips.Remember that the power adapter charges the battery pack as long as its plugged into the computer and AC power source. Be aware thats it takes much longer the charge the battery pack and when the Eee Pad is in use"
Remember to fully charge the battery (8 hours or more) before the first use and whenever it is depleted to prolong battery life. The battery reaaches it's maximum capacity after a few full charging and discharging cycles.
"To prolong Battery life, charge the battery for up to 8 hours when using Eee Pad for the first time and whenever the battery power is fully depleted.

Battery Life: 1d 12h?

Using Faux rom (Kernal version 2.6.32.41-CM7-Faux123-v0.2.3)
I was able to get a crazy amount of life out of the G2x! Anyone else able to get some times like this?
When I first got the phone it would only get about 4 hours.

i've been on 11 hours, Nexus AOSP, and am at 85%

With SetCPU and underclocking when idle or on calls?
Is Juice Defender involved?
Exclusively on GSM?
Are Auto Sync and GPS off at all times?
Please provide context.

Yes, setcpu and some UC, phone goes to min processor on screen off
Juice defender set to standard
data set to auto
auto sync gmail, gps only on demand
note today was a very, very light day of use. Yesterday I used it moderately, checking emails, maybe a call or two and several hours of music and was at 50% after about 14 hours.

I have tried virtually every ROM and kernel combination for the G2X and for my phone and usage pattern I have had the best luck when I returned back to CM7, currently RC1 without OC/UV kernels, without SetCPU/PimpMyCPU, and without Juice Defender, or any similar such programs. My gains appear to be achieved by better efficiency with the screen off. The only modification that can be responsible other than CM7 itself is that I have the phone 2G only unless I need 4g at which times I turn it on manually. I think this is the actual cause of most of my better battery life.
Recently I went 32 hours of light usage (maybe an estimated 3 hours of phone calls and 2 hours of actually performing some task in Android) and was at about 35% battery life (although I believe battery percent is totally meaningless on this or any GB Rom for the G2X). I can easily make it sun-up to sundown with moderate to heavy usage unless it involves lengthy playing 3d video games or similar cpu/video intensive tasks.
When I first had the phone (completely stock) the battery would run out before 8 hours even if I didn't use it at all. I think I was getting great battery life with the AOSP ROM (Faux) and Eaglesblood ROM without modification. I am came back to CM7 rather than those others for purely aesthetic reasons.
My conclusions are merely based upon extensive trial and error and subjective impressions. I am not an expert at anything, except perhaps backgammon, lol

2g only is not a fix in my opinion. I purchased a 4g phone for a reason. The software and drivers are still an issue. I get a solid day (12 - 16 hours) out of a single full charge with 3 email acounts checking every 30 min. Surfing the web and a little game play for fun. The screen is the biggest draw on the battery. My battery monitor shows a direct corolation to battery draw and the screen on.

I understand your point, but how often are you actually using 4g. It is not necessary for syncing email or other background tasks, in fact on my phone Pandora runs the same on 2g as 4g. And when you do need the performance of 4g it is 2 clicks away, one swipe to pull down the notifications and another to toggle from 2g to 4g. It connects in about 10 seconds, for me anyway a shorter period of time than it takes me to figure out what I'm doing. 4g appears to be the biggest battery draw with screen off. If you use JuiceDefender you can program it to turn on 4g whenever particular programs are launched.
You are right about the screen it is certainly the biggest draw with screen on. I run a bike computer with gps program. I run it with screen at full bright constantly on, gps running, plus using whatever small amount of use the program uses to operate. At this rate the battery runs out before 4 hours are up.
Oddly making phone calls appears not to drain the phone at all compared to other activities. I've taken my phone of the charger and made a 1.5 hour phone call and hang up and the phone is still at 99%.

23 hours and counting on this charge...

i can get that time on my stock rom one time my phone lasted 1 day 15hrs on stock rom.

I have no doubt, there is nothing inherently wrong with the stock rom as long as you root it and get rid of the bloatware. Getting bad battery life is more a matter of something being wrong, instead of a particular rom being right.
I don't really understand the battery info built into Android, my uptime right now is just over 16 hours and I am at 25%. Which is good as anyone can expect with normal usage. But what is confusing is the usage breakdown, it lists most items at exactly 19%, Cell Standby, Wi-Fi, Dialer, Android System, and Phone idle. Voice calls is the only other item at 6%.
What the heck is Dialer doing with 19% of my battery!?!?

16 hours so far with 20% left.
8 hours of that was while I was sleeping.
While there was some screen-off time for the other 8 hours, the tasks I was doing included redownloading ALL of my apps manually, applying themes, configuring widgets, browsing xda, email, light texting, and a couple short calls.
I am running CM7 with stock kernal. I have like 40 widgets running (probably an exaggeration). I'm running Juice Defender set to disable data/wifi when screen turns off, and enable it for 2min every 15 min. I also have setcpu running. I increased the min to 456 instead of the default 216 because it seems to keep me from experiencing the black screen of death when I leave it higher. My screen-off profile is 456/456, and my in-call profile is 608/608.
Overall, considering that I keep all syncs set to auto so I get instant notifications of gmail and sms, and it takes all of about 3 seconds to turn the data/wifi back on when I turn the screen on, and I don't have to constantly go back and forth messing with 2g/3g. I am extremely pleased with this phone now.

Been unplugged since I woke up this morning...13H 57M and have 40% left.
That's sending many texts, tweets, and using the GPS app for my round of golf today.

currently at 2 days (actually 1d, 23h, 44m) and I still have 30% left. I would say light to moderate use.
Currently running cm7 on nightly 65 with the stock kernal. No setcpu/pimpmycpu or any juice defenders.

battery drain?

hi guys, i'm wondering if theres something wrong with me nexus s cause it drains battery really quick.
settings:
wifi - always on
background data disabled
display on lowest brightness
using go launcher
use phone couple hours a day. (maybe 3 - 4 hours on display?)
by the end of the day, im at like 10% or less battery. (unplug around 8AM and 10% around 15h later).
i went to sleep yesterday on full battery and didn't charge. woke up and i'm at 75%!
email seems to be the biggest battery drainer apart from display. i don't even use my email that often, but it always comes back in the 'running applications' list.
any way to fix?

What's your current setup? Are you running stock or a custom ROM and kernel?
A ~80% drain in 15 hours is something I have too btw, but some people get their device to last almost 2 days. Based on your usage, you should at least get around 20-24 hours.
One of the best enhancements the custom ROMs gave us, battery wise, is the Deep Idle mod. That'll make your battery drain maybe 2% over night.
You say the E-mail app is using the most battery... Maybe it's constantly checking whichever server you connect it to. The native Gmail app had battery drain issues in the very first releases of GB but those have been worked out a long time ago.

thanks for the reply
i'm on stock rom, no root.
also im using the email app not the gmail app (not sure if it makes a difference) and i set the update interval to never.

Can you go to Settings => Battery - Click the graph and post the top 5-6 stats from that list please?
Also, which version of Gingerbread are you running? The last one? (2.3.7)
And apparently I was mistaken, it was the E-mail client and not the Gmail client that had reported battery drain issues before:

just went from 83% to 66% from listening to uber music for half an hour and playing 10mins of angry birds at the same time...
tempted to root my phone just forbthe battery life. lool

That's not too abnormal, gaming asks a lot of the battery.
What is stopping you from rooting and trying out new ROMs? You have Nexus S after all, the possibilites are legion
