Upgrade from Eclair to Serendipity(Froyo) Battery Doesn't Last

I've viewed many posts on battery life on xda but I still don't know why my battery doesn't last even when I am not using it.
I disabled wifi/gps location, disabled facebook/twitter widgets and any other logical power usage. After that I powered it up to 100% and after two hours with no usage the battery dropped 15%. I installed an app which will let me know in a day or so which apps are sucking the life out of my battery.
Do you have any ideas?
Thanks

Recalibrate the battery.. lots of info on xda. Mine went two days the last charge...

You might have flashed it when your battery wasn't full?
try recalibrating the battery?

That doesn't always help. I had the same issue with Serendipity. It is a good ROM but for me it just killed my battery. It was mostly draining during sleep periods which it should not. I have had issues with OC/UV kernels and I just decided to switch ROM's rather than try another kernel. Nothing wrong with the ROM for me other than battery drain, which is an issue between phones from what I have seen.

try firefly + speedmod kernal
give it a few days to settle in after 2-3 days use my battery life had improved tremendously

Since flashing to Serendipity my battery life has just about doubled from ~6 hours to more than 12 hours of heavy use.
I use WiFi, GPS and Bluetooth continuously with very little3G data or voice communications.
I never use the media player or the camera.

Try the Di11igaf's 5.1 rom. The battery is amazing for me. Just flash the rom at 100% and then recalibrate and set clock at 100mhz and uv at 50 75 75 100 125 125 (1280 to 100mhz)

Serendipity isnt the problem ...

Agreed. I believe it's user error.

The culprit was wifi, as it would randomly connect to a network and some apps started to sync. I"ll try to recalibrate the battery and disable wifi for a day and see how my battery lasts.
Thanks for all the help

Re flash baseband?

I have a g2x that has absolutely horrid battery life when using WXCDMA. When using it on the go, I sometimes loose like 1% life per minute or so, getting quite warm in the process. Also, when these monsterous drains occur, it continues killing the battery while sleep.
When on wifi, the life is great. I have already tried all of the various fixes, but I haven't run across anything that would stop the wcdma modem from sucking so much power.
I'm wondering if reflashing the baseband would work? Is that file even available? Input is greatly appreciated, cause I am envious of people that can make it a full day on a charge....

"Flashed multiple roms" isn't helpful. Which roms did you flash? Have you tried CM7 or one based on CM?
Have you monitored your battery usage to figure out which apps are eating up your battery?
Do you turn GPS/bluetooth/wifi off when not in use?
Replaced battery (seems to help people who have over heating issues)?
The most common causes of the battery drain/overheating is a rouge app and/or just a bad battery. My battery never even gets warm. I've noticed that even after long periods of gaming or internet surfing that the phone is relatively cool, so it seems you definitely have a problem there. Finding that problem is key.
Before you jump the gun, my SETTINGS>ABOUT PHONE>BATTERY USE:
Cell Standby = 58%
Phone idle = 42%
Display = 2%
I don't know why that equals 102% but just roll with it. A good battery monitor app will tell you which specific application is eating battery. I don't use those as I don't have a need to since I don't have a problem, but check those out and report back.

I have a brand new sim card.
Yes I have tried cm 7
I haven't tried a new battery simply because its not the battery that gets really hot, its the phone, specifically the area around the camera lens.
Also it doesn't do this while on wifi.
Sent from my LG-P999 using XDA App

I think the processor is around the camera lens. I tried flashing a rom that would simply not boot. It would go from the LG screen to a black screen and hang. That is the only time my phone has been warm around the camera lens.
So try to figure out what is taxing your processor and stop it. What rom are you running? You still haven't provided enough details. What about a battery monitor? What apps do you have installed?

Nothing was taxing the processor. This has happened on the stock rom with no added apps. Surfing the internet is what made it warm. I used an app called watchdog to see the cpu usage and nothing even went above 40%

[Q] Battery draining extremely fast. Any suggestions?

This rom used to be fine, now it is draining extrememly fast and I don't know why.
I am on Gingerbread KF2 and really haven't done anything else yet. I used to be able to make it through an average day of ~15 or so hours using the phone only for some messages, a call or two, and a few minutes of music. After this type of usage, the battery would be around 70-80% at the lowest usually. This is even with the screen at FULL brightness all day.
About a week ago, it started draining super fast. The same usage runs the phone down to about 20-30%, which is ridiculous. In battery stats, Android OS is always FAR above everything else with like 60%. A couple battery calibrations did nothing. I don't use task killers, but I do check my running apps. OS monitor didn't help me at all, and checking my currently running apps just showed mostly system apps that should not be draining hardly any battery at all.
Any suggestions? I think that about covers it all. This just has me stumped...

go through your apps and see how often they check for updates. there were a lot of updates recently and some settings may have changed. If nothing changed, can you do a quick scan with look out? Just to be safe. Also, try juice defender and set it to aggressive

Lookout didn't pick up anything and I set JuiceDefender to aggressive. Will JuiceDefender warn me of an app using excessive battery?

Nope, that battery is still dropping like crazy. (8% in half an hour from almost no use.)
Maybe I just need to reflash and start over fresh...

It will take a day out two to settle in. is your phone sleeping properly when the screen in off? Press the volume keys once it locks and if it makes the sound then it if still on.

Sleeping just fine.

Yea, I guess if you can't figure it out, you can reflash. That is a pain though. I would say to try out jd for a while longer and see if you get results. fb us usually the culprit for my battery drains, but if you checked all of your apps and changed them to manual, then there isn't much more you can do.try putting your screen to auto brightness

So either juice defender is helping or ADW launcher was using excesive battery. It is working better today after I switched back to launcher pro, but still going down pretty fast.
Sent from my SGH-T959V using XDA App

ADW doesn't really drain much battery for me. It actually uses less RAM compared to LauncherPro and Go Launcher (for me).
I think you should just try reflashing your ROM, maybe flashing the new GB ROMs too.
Also, are you sure you're doing the battery calibrations properly? That might also be an issue.

Maybe it's not your phone or ROM...
I've had several ROMs in the last few weeks and have noticed this behavior on many of them....after searching, I found this.
T-Mobile has apparently noticed some abnormal battery issues in areas with their "4G" HSPA+. They're asking people in their support forum for a bit of info to help them find the issue.
support[dot]t-mobile[dot]com /thread/3544
The problem was initially believed to be affecting the G2 only, but is now believed to be affecting all phones in their "4G" footprint that started when they updated their towers in late July. The update provides the government an emergency channel to use, but it appears that it may be causing network issues.

Thanks for bringing it up, this is affecting me too. i lose 20-40% battery PER HOUR of use on the phone at 25% screen brightness playing a card game online (no wifi, just on HSPA+). This is on a BRAND NEW flash of KH2 (GB 2.3.4).
The top half of the phone gets really hot and battery drains like crazy. ceasing data use cools it down and reverts to normal battery use.

Are there any others s4 owners out there noticing BAD battery life?

I've seen a couple threads praising their s4s for how long the battery life and in one case how much it flatlines while it's idle.
Since I've had mine , I've noticed the opposite. Using it very casually throughout the day with some light texting it'll drain probably about 30-40% while doing very little of anything.
But the part that stands out the most is when my s4 is idle overnight , it'll drop about 17-20% while others have reported seeing very little loss.
Has anyone else expierenced poor battery life? Is this normal for my s4 to do?
The only features I have turned on are; Wifi, Sound, Mobile Data, and Sync.

Seems you have a run away app that is sucking your battery. If you are rooted, check out Better Battery Stats on xda. I get at most ~2% in an hour but normally its not even 1%.

Weird.. I don't think I have any apps that are running wild in the background. I'm not rooted atm though.
If it were a mystery app running in the background, would it be listed on the battery stats screen showing the % each program is taking up?

You said you have sync enabled, how many different accounts or apps are syncing and how often? If you have 4-5 accounts syncing every 15 minutes, your phone will never sleep and you will see massive drain

One of the problems I had when updating to my new S4 was the memory card. Going from the S3 to the S4 was not good. The S4 didnt like the memory card and was causing high Gallery cpu/battery usage. Reformating the card fixed that problem.
Now, my Galaxy S4 has the best life of any Android I have ever had. At the end of the day, it still has 40% battery remaining with an screen on time of around 4 hours.

I think you're aiming in the right direction here. That was one of my guesses was that sync is draining it fast.
Just checked what i had under accounts. The only ones that were syncing were Google (toggled off a few of the features i don't use so i only sync what i do use, drive , calender etc)
The only other one that was on was Samsung account which i just toggled off as well since I don't have any need for that to be synced up whatsoever.
The only other apps I can think of that actively try to sync are my gmail and facebook. I'm not sure how to view the frequency for gmail to sync, but facebook is set up to check every hour.

Yeah I have more accounts than that and I see 4+ he's of screen time a day with 30-40 percent left at the end of the day. I would try formating your sd card as stated above as that is also a known problem

Not I personally. My buddy his wouldn't charge past 46% no matter what. Not even with new battery or after a factory reset.
I tho notice better battery life with this phone then on my s3.

I don't have a sd card inserted

Here is mine on little usage. About a good 2-3 hours of screentime, everything turned on, max brightness, and live wallpaper...
I also had a 64GB MicroSD from my Galaxy S II that I did not format.
From the screenshot, the MediaServer is from the live wallpaper, and Maps -> almost every location setting in maps setting is checked... which will change soon... :good:

FWIW, GSMArena did a new battery test for the i9505 after the recent OTA update:

Overall, it saw a slight improvement.

Yea just checked bbs and it showed that any smart screen feature turned on caused wakelocks 7 hours straight while I was sleeping. disabled and Now I barely get battery drain and my phone goes into deep sleep. Sucks cuz I liked using smart screen features.

I'm getting itty good results I think? Formatted memory card installed.

Look on XDA, its free.
Also after the OTA update my battery life is about 2x worse. Before I would lose 1% overnight and now i lose about 3%. Before I could get 4hrs screen on time with 20hrs standby, and now I am at 35% with 10 hours standby and 2hrs 6min on screen on.
Going to factory reset tonight.

I have only slightly better battery life than my rooted inspire 4g with a 1230 mah battery....
I cant WAIT for the custom roms and developers tweaking these phones...there is soo much potential for this device!

Are you using a battery saver?

I'm using Green Power for a while now but lately I have been thinking that it might not be needed anymore.
What are your thoughts and what are you using to save battery.

Personally, I think they're a placebo effect, but I never gone in depth to do any real comparisons so I could be wrong. And the M8 has a good enough battery to where I don't consider needing a battery saver.

I ran Qualcomm's Battery Guru app customized for our CPU on my Rezound and now my M8, but ultimately decided that I would just run in standard powersave mode. My kernel lets me undervolt and overclock, so I get decent battery life coupled with fairly good performance without ruining any other battery software.

I use the built in batterysave in CleanROM combined with ART. Great combination.

I use the built-in Power Saver, along with Greenify.

What ever for? [Imgur link, SFW; shows my battery stats this morning]
If I can get 20 hours to 30%, I can probably get 30 hours on a full charge. But I put my phone on the charger when I go to sleep. If I didn't, I'd be shooting for a 40 hour drain. That's kind of high expectations for a stock battery. Why not just charge it every time you go to bed?
I'm running the latest CleanROM in Dalvik mode, whatever kernel comes with it and zero battery saving apps. I do have the option ticked as you can see at the link where it cuts off your data when the screen is off (like Deep Sleep Battery Saver, and others). But the battery saver itself is off.
