Ive just installed CM7 today on my Galaxy 5 and the battery life is beyond awful.
Its dropping to 15% from 70% in under 30minutes, its not the signal im positive. It was fine before i installed CM7- any help?
I think some application is sucking your battery life. I have the same setup and I agree the battery is bad but not that bad. It lasts for a almost a day.
Recalibrating has seem to of done the trick:')

i've been running Nero 4.1 since it was posted and battery life was fine, suddenly last week it has been cut in half. I didn't load any new apps or change any of my settings or usage habits. I was getting 25+ hours and now I get 16 tops with very light usage. My battery stats say display is using 73% but the phone is idle most of the day. What could have caused this? Also I have tried conditioning the battery, it didn't seem to make a difference ,and, I flashed the rom with 100% charge.
did you condition it right?
I've been on Bionix 1.2.1 for about 2 weeks and had relatively good battery life.
Suddenly, my battery life is going down really quickly. About 10% every half hour. I didn't update any apps, or install any new apps during that time. I've checked all my apps to make sure they're not downloading data too often.
As a last resort, I've reinstalled Bionix and the Ka7 stock kernel again as well. Now it seems intermittent. Battery life will be good for 2-3 hours, then rapidly drain, then OK for a 1 hour, then rapid drain.
I haven't been using my phone at all, just turning it on to see the battery life meter. I've checked the Android "whats using your battery" and it's only listing "display93%" "standby 3%".
Any Ideas?
well if you have wifi calling installed on your phone that might be what is draining your battery
that app is a a battery drainer even when not in use
Thanks for your reply Dgameros, I couldn't manually uninstall it so I re-flashed Bionix without wifi calling. Battery life seems to be better now!
My brother did the OTA update last night, his phone has never been rooted.
After about 5 hours today his battery has about 20% life left! Battery stats says 74% of the power was used by the display which was on for 40 minutes.
Cell standby is about 4% of battery use and he was without signal for 25% of the time, if I recall correctly.
Anyone else observing something similar?
My battery life on 2.9.2 has been less than desirable and I was considering going back to stock in hopes the battery would be better after the OTA. This is not encouraging.
Also, does he need to go through a couple battery cycles, drain fully then fully charge, before he gets a clear picture of what the battery life would be?
TIA
Yes true battery life will be clearer after a few days of use. The phone learns your usage and gives a better idea of how much charge is left.
best way is to fully charge battery and then wipe battery stats and then drain battery and then charge battery to full one charge. Then use phone normally for s couple of days. Then you will hadn't good sense of what kind of battery life you are getting.

Thanks for the response.
Am I correct that he would need to root to be able to run the battery stats script or is there another way?

I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...
I agree, the OTA froyo ED01 is worse for battery life. I get 5-8% per hour idle drain, which is way too high. I've been try to track down the issue with spare parts, system pannel, and battery details. So far I can't see any specific issue.
There are so many hoops to jump through just to get this phone working normally. It's really insanity that we should have to bust our butts on software bugs. And this isn't even mentioning the totally slow choppy ass browser in 2.2. (Vibrant browser on 2.2 SO much better)
Overall my urge to flush this POS down the toilet is growing every day.
My battery has horrible life. I'm rooted running evil fascination and have done all the things that typically help with battery life such as disabling gps and wifi, and lowering brightness. In fact my brightness is currently as low as it gets and my battery use shows my display as 99% of my current usage. Even though I just took my phone off the charger 15 minutes ago and it's already at 85%. I know my screen can't possibly have taken that much battery so fast. It also takes about 4 hours to charge from zero to 100 because it's draining so fast. Can anyone give me some advice? I downloaded an app that shows my current mah or whatever but I don't know what that means. I notice when it's at 270mah my battery drains fast which is most of the time but a few times it has been at 2 mah and it doesn't drain fast then.
sounds like a rogue app keeping your phone/screen running when off.. I had the same problem a while ago, 96% screen usage and taking 6 hours to charge then draining to zero in an hour and a half.. unfortunately the only thing that fixed it for me was a complete data/cache wipe and reflash of the rom, I think I was on superclean 2.9.2 at the time.. could be the battery being wonky also, you might wanna look into the battery calibration app on the market or wiping batt stats in CWR

Yesterday I decided to try a cm13 Rom which was working very good until it rebooted when I tried the v gesture for flash light. After that it was working the cpu on 100% all the time so I wiped everything and restored my old cm12.1 Rom after wiping. Today my battery life was horrible, around 2h SoT with no standby, usually I get around 7-8 hours with a lot of standby time. Did my battery get ****ed by the heating yesterday or what happened? I've never restored a rom before, can that have ****ed it up somehow? I just don't understand, I went from incredible battery life to buy a new phone asap battery life.
Edit: seems to be a battery calibration problem only. Have been on 1% for over an hour of SoT and some standby too.
How do I recalibrate the battery? My battery goes to 1% in 2 hours and then sits at 1% for ťhe rest of the day. Battery life is normal but I have no idea how much I have left.
Went into twrp where the reported battery % was correct and now when I rebooted system I'm up at 84% from 29 lol. Hopefully it's fixed now
