I'm Getting Great Battery Life!

I installed OMGB-6 when it was released. Then flashed invisiblek #21 kernel and the new market. Since I last charged it, I've talked on it for about an hour, used the web-browser (Skyfire) fairly moderately, sent a few emails (Gmail), and spent a total of about an hour of GPS through the application WAZE. I'm left at 22% battery left after about 22 hours of use.
I've been fairly lazy with regards to changing the screen brightness, so it's been on about 50% brightness. I've left sync and gps on during the whole time.
I've been using Watchdog as a smart task manager. I have SetCPU installed, but I haven't used it at all.
Here are some pics:

I have not installed the kernel but my battery life is terrible. I barely have any apps and I do not use my phone a lot. I love the rom (favorite by far). Should I try to install the kernel.

Can't hurt, just nandroid first, or have a spare kernel handy.

I chewed through my battery in about 10 hrs today with the same kernel.
Guess I use mine a lot more. I've also got 26 hrs out if it when I barely use it.
Don't think you get great battery life when you don't use it much.
I'm in CM 6.1 but that wont really matter.

True, I haven't been using it all that much. But compared to other ROM's I've used, this get much better battery. Everything else I've tried out got me a max of ~12 hours even on idle the whole time.
Definitely try to install the kernel. Can't hurt! Just make sure you always have a nandroid backup available.

Stock Battery?

50% Brightness?!?!?! Wow....battery life is not worth looking at a dull screen. 100% all the way for me...im using 1800mah from ChiChitech that I got for $20. Seems to help enough.
I'm also running a Gingerbread ROM (Evervolv a17) but can't tell what difference it's making on battery.

Hydra 1.13 overclock kernel, stock ROM, stock battery, auto-brightness. I'm currently at 20% battery after 2.5 days. Light usage over the weekend, but there is an hour and a half of talk time in there and a half hour of reading.
The trick to DI battery life is keeping the data network usage/standby under control. If you're trying to send/receive data with no signal, the phone will burn through its battery in 4 hours and I've used 20% in 15 minutes trying to book a flight on a low signal connection.
Realizing this took me a few months since I live in NYC and as such, go through a lot of signal shadows. Some days my phone would be at 50% battery after 12 hours, other times it'd be dead after 6. I now realize that the short days were caused by sync services trying to run when I was in a shadow. You can diagnose this for yourself by going to the cell standby section of the battery usage. If you're over 10% or so without a signal, you have this problem.
You can handle this manually by holding down the power (on the stock rom) and enabling/disabling mobile network. This is a pain in the ass.
I handle this with some simple Locale rules along with the Mobile Signal and Mobile Data plugins. The first is to shut off the data when there's no signal. The second is to shut off the data at work where I'm usually but not always on a wireless network. The third is to shut down the data during my normal sleep hours and airplane mode if I'm at home.
These easily got me to 36 hours so I grabbed an undervolt kernel, which gets me to 2 days of regular use. Daily I do about 15m of talk, 40m reading news/email on the subway, and another 30 mins browsing/messaging/misc. My monthly data use is ~350MB.

While it is likely true that the OP and others have good battery life under their specific use conditions, battery life in general on smart phones is mediocre to poor at best. I have friends with various different models of smartphone (including iphone) and across the board battery life is not good. The exception is blackberry, but I don't consider those competitive from a tech and feature standpoint. Obviously different people are going to have different opinions and experiences based on the various factors that influence battery longevity.
The solution is to stop worrying about it, get a spare or two or three and pop in a new battery when one dies. This imo is one of the best things about the Dinc and Android phones in general. Just my 2c.

CM 7 weird battery behavior

I noticed this. Usually the screen uses like 80% of the power after I used the phone for 5 minutes. This is after a night of my phone doing nothing and me playing around with it for 10 minutes or so. The phone idle and cell standby are really really high for some reason.
I did a reset of my battery stats but this didn't do anything.
When I was running stock sense with 2.2 it never gave me this result. Those two were always maybe around 2 or 3% or so so after a full day of use. It's weird.
Anyone else dealing with this?

5 to ten minutes isn't really an accurate capture, have you given it a full day and then checked the stats? After five minutes it completely stands to reason that in that five minutes the display used 80% of the overall draw that happened during that span, does that make sense?

Same thing here. Used my phone for the whole day and the Mobile Standby used up like 40% of the battery. Mind you, there was a trip today so i used it for pretty much anything from playing games to downloading market apps and listening to music.
With the stock 2.2.1 Sense my display used up 80-90% of the battery all the time.

^Exactly. It makes much more sense that the display uses the most energy by far.
Half a day later.
Still seems weird to me.

It doesn't make sense at all. This is after almost a full day of usage. I've been calling, surfing and playing games on my phone.

Battery almost empty stats.
Sent from my HTC Vision using XDA App

I kinda figured it out. I just switched to use only 2G networks and now Mobile standby uses only ~35% of the battery. That's still too high, though.
Sent from my HTC Vision using XDA App

I'm gonna try that on my next charge. 30% is still very high though, it should be less than 5% or so I think.
Sent from my HTC Vision using XDA App

Can the radio affect the battery usage? If so, then shouldn't flashing some other one yield different results?

I have similar issues with cell standby being unusually high. My phone battery only drains poorly in one location (work) however. It will go from 98% to 15% by about lunch time even though I haven't used it. Disabling cellular data and wifi does nothing to improve it. Only airplane mode seems to stop this behavior. I have wiped battery stats and conditioned the battery and am at a loss on how else to troubleshoot this problem.

Removing WIFI calling and GanOptimizer using TI Backup has improved my battery noticeably thus far. Will need to further test over the next day to see if this was the cause of my battery drain. Here is the post I found concerning these two apps. It seems GanOptimizer puts WIFI in high performance mode. This happens when not using WIFI Calling (think you had to have used it once and then turned it off). My thoughts are that it causes WIFI to not sleep (ignoring the policy in the process) and leads to excessive battery drain as WIFI is basically running full power constantly.

i think how it work for the rightway?

Hmm... I dunno. There seems to be something weird going on with the reporting itself. This is after another day of use. I used navigation for maybe 3 minutes or so. When I look at the detailled view of that, it shows that it didn't keep the gps on or anything. It just doesn't make sense at all. I did many other things as well. Calling, texting, browsing, youtube etc. None of that is in that list.
A lot of things just don't show up in the list for some reason. Notice the display isn't even in there?
This is a fresh install that's 3 days old or so and. I don't have battery management apps or app killers installed.
Sent from my HTC Vision using XDA App

Well so much for an improvement. Came to work with battery @ 96% and two hours later it was at 69%. Android System now is apparently consuming the most with Cell Standby a close second. Think it is time for a phone wipe and slow installation of apps one by one to find out what is causing such excessive drain.

Well it seems like the error is in the reporting itself. The stats don't make sense at all, but my battery life is a lot better than when I was running stock sense.
On a side note, oh what a happy day today!

I've been noticing the same odd battery usage on cm7.0.3. the past few days, getting 32% for cell standby and 25% phone idle :S. I've never really had usage this high for any rom except cm7, usually its my display around 80%.
I'm still getting average battery life (~18hrs on a charge) but nothing like the amazing battery life with rmk's g-lite 1.0.2.

battery life

Just thought I'd give a quick review of Cyanogen Mod 7 battery life and performance.
Standby battery drain of about 1.5%/hr with 3G, backround data on, auto-sync on, wifi on, GPS on.
I've never obtained such great battery life on any stock rom or stock-modified rom (I've tried a few different ones over the last year or so)
The performance is also much better than any of the stock-based roms (no lags).

No need to create new topic for that information.

fan/zombie boys everywhere
aple has ones so why not android ;]

Which nightly are you using? Which kernel?

After a night my Galaxy S is always dead. I solved the problem disabling 3g connection and sync. Stock rom 2.3.3 and semaphore kernel.

Sorry to say but useless thread. Just keep the damn charger always near you and battery life wont matter.
Btw did cyanogen pay you for posting this?or........

haha I had the same thought

I used to always hear about CM7 having god-awful battery life. I don't know if people were lying or if they fixed some major bugs, but I certainly have no complaints about my phone's battery life (running CM7, of course). I get through way more than a day.

That's my current battery stats. Haven't used the phone too much the last little while, but getting over 24 hours is not uncommon—I actually very rarely see my phone last for under 24 hours, and that's usually because of 5+ hours of screen on time. For that battery, I'd say about 75 texts, 30 minutes of phone calls, and about 30-60 minutes of web browsing. Fairly light use, but nevertheless, the battery life on CM7 is nothing to complain about.
EDIT: Looks like something was causing a wakelock the last ~6-8 hours while I was asleep, causing my phone not to deep sleep. If that hadn't of happened, it would still have quite a bit more battery (when I went to bed it was 44%, so it shouldn't have dropped to 27%—it should have dropped to ~40%). This just proves my point even more: battery life on CM7 is not bad at all.

seriusly?
do you see any battery change in that period compared to one earlier ))
when it was awake on your funny screenshot it was discharging with the same when the phone was not awake acordding to that stats so no impact registered

Thanks to share that information...

Best battery life that I've seen, using cm7.1 stable.
Currently at 2 days 1hr 15 mins with 14% remaining.
Wipes the floor with friends phones on stock roms charging every night. I only switched toCM7 after darkyrom barely lasting 12 hours at times

This sounds fantastic, Cm7.1 is my next choice, on XXJVT battery life is only 12h

thats using juicedefender to activate the data connection when screen turns on, emails still push to phone straight away with gmail so it is fine for me.
WIFI seems to drain the battery a bit quicker but not enough for me to bother flashing different kernels

I saw someone who did 2 WEEKS without charging. Normal using with black wallpaper on 2g network.

seems to be even better on ics... the best i had was ~2% per 8 hours...

3G + WiFi + email max 1 day

ICS battery life

Getting some great battery life on evervolv's ICS rom. Anyone else getting similar performance?
EDIT: Today im at 50% with 12 hours use... some tiny tower, about 20 mins of phone calls, gmail, google voice, and facebook sync

wow.. good for u.. my nexus one only last for about 15 hours.. btw, i'm using the medroidmod ics 1.4.0..

That's good. Might be a glitch though if your battery is not calibrated. I had an issue when my N1 was showing over 20% and then shut off. When I turned it back on, it showed 0% and turned itself off. Try to discharge it all the way and see it if will shut off before it hits 0%. I would do it as a precautionary measure just to make sure that your phone doesn't die unexpectedly when you need it most.

nice battery life mate

I have calibrated battery and it lasts around 12 hours with fairly good usage.
But my mobile shuts down when battery at 15 %.
Do I need to calibrate it again?

This will not help. I have calibratet again and again. I'm using the medroidmod ics 1.4.0.
My phone shuts down on 15%.

what are you guys using to calibrate for your battery? Mine used to turn off around 20-25% remaining but after I reset the battery stats its been more accurate. I get nowhere near the same amount of battery life that the OP has but I also am in a bad reception area.

I'm on the MeDroid HWA Mod and I cannot believe thatmy battery lasts for about two days now.
Do you really recalibrate or do you use the function out of your recovery, which function is busted meanwhile?!

Would like to find out about this battery calibration as well. Battery life on my N1 hasn't aged well, and I wonder if the batt's showin its age or something.

Mine isn't that good
I'm on latest MedroidMod but my battery drops fast with screen on and wifi but data off. It's like 20% each 25mins. But ICS is so sweet and cool that I don't wanna go back to the buttersmooth GB.
P/s: Which home launcher are you using/do you recommend to run on ICS?

My battery life seems to have improved slightly as well. I guess the complete redesign Google did, has done some good

wow its amazing

I'm running medroidmod remix and I'm happy when I make the day with one charge.
When my screen is on you can almost see my battery discharge.

With texice i had a huge drain (10% per hour), with medroid it was a little bit better but not nearly as good as with cm7.2RC1 now.
I've also finally updated radio to 5.08 yet.

58% at 12 hr's moderate usage on dk's rom (u5).

Normally Ive never had a problem with the battery, ive lasted about a day and a half on moderate use, but with the latest version of BCM U5, when my phone goes idle for a while it starts to drop significantly, i'm not sure why its staying on other than I might have gotten a notification and it decided to stay awake

DK ICS latest update has a really awesome battery life, as well as a very good performance. recommended ROM 100% =)

Could 7.1.1 battery drain be from apps not optimized

Optimize all apps on 7.1.1system apps is there a fast multi select way
Noticed upon boot never does it and after looking into battery history telling me to do this but setting's menu under apps don't have a method . By the way this is on pure nexus ROM.
7.1.1 seems to drain the life fast and my device is new 3/days old
Sent from my Nexus 6P using XDA-Developers Legacy app

Pure Nexus isn't great for battery life compared with other ROMs I've been on. Android doesn't allow some apps to be optimized. If your battery life seriously concerns you then you might want to try an app like Naptime which puts your phone into deep doze as soon as the screen goes off. You could also download a kernel manager if you don't have one and see if you are using a performance oriented governor or something more battery friendly.

If your phone truly is brand new, you're going to need to wait longer than 3 days to achieve optimal battery life. What is the date of manufacture in recovery>>barcodes? There are a few good apps that will tell you definitively what is draining your battery. BBS and GSam are two. It is also a great time to install Accubattery and get a benchmark on your current battery capacity vs. design.

The problem is not with stock Android 7.1.1. It could be your battery is defective or degraded. That's why I asked if your phone really is "brand new" or refurbished, and what the date of manufacture is. Install Accubattery and use it to calculate your battery's capacity vs. design.

Last few months my battery is also getting worse. Accubattery says capacity is around 2000mAh right now. I did often charge my battery, even when it wasn't below 50%. Maybe that killed it.

Not your fault mate, regardless of how you charged it. Battery was defective. Get an RMA if you can through Google or Huawei (even if it is out of warranty). If not, there are a few places selling good replacement batteries. Install yourself if you can, or take it somewhere to have the battery swapped out. Good luck to you.
