I am looking for the name of the battery stats file and where it is located, on my installed rom Trigger. I updated this rom but my battery life is poor. On a older version it was great. Yes I wiped the battery stats after conditioning my battery. Many ppl have good life with the update so something is different with my setting or something. What I want to do is pull that file from my back up and put it on the new version. Back in the day of my Behold 2 I and many ppl put the batterystats.bin from BH-MAN aka "eugene373" phone to ours and my battery life increased 50 percent.

Has anyone else experienced any problems with their battery stats resetting themselves? Mine used to be accurate (at least in terms of running time since unplugged) -- but ever since I flashed to 1.5.7 (and got tremendously better battery life) -- when I check later on in the day I notice the stats seem to have reset at some point in the day.
This morning I unplugged at 8am exactly, and now checked at 7pm and my battery stats claimed 8hrs unplugged ....
Anyone else have this problem?
i am thinking that my battery life has gone down since applying the update, so i deleted the batterystats file last night and charged it over night.
i did not notice that the stats you mentioned were an issue on my phone, though. one of the few things i have been looking at is the uptime, and it seems to be accurate.
does anyone know for sure if the batterystats.bin file should be deleted just before the battery dies, or after a full charge on this phone?
I'm not sure if it's the same with the Atrix, but on my Samsung Galaxy-S we used to delete batterystats.bin right after full charge, then it would create a new one automatically and begin tracking.
where is it located on the Atrix?
Thanks!
i used root explorer to find it under data/system/batterystats
after you deleted the stats from a full charge would you drain the battery until it turned off or charge it whenever you felt like it?

Personally I would drain it until the end --- you're trying to gauge a full battery's worth right? Charging it mid-way wouldn't tell you much
thats what i thought too, but i havent done that in many months (since i had my nexus 1 and was flash happy). i did a search in this forum last night and the only thing i found suggested wipping the stats when the phone was almost dead, then charging with the phone off until full. in my head i thought delete the stats from full and then let it die, so i was unsure as to which way was right
Ok so I just tested and realized the battery stats RESET after a REBOOT ... doh~
Is that normal for everyone else?
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.
hi.
I am using CM7 now which is great, but since I am going to a trip abroad I need to temporary change to a ROM with GPS, but most inportant, with a great battery life.
I don't need any great performance like CM7, I just need the battery to last long.
Any recommendations?
Thanks.

from my experience best battery i have on this rom i flashed this rom yesterday and charge it to 100% and run batt calibration it is preinstalled in this rom when you run batt calibration after that unplug your phone from charger and use it till total discharge and do not turn your phone on charge it to 100% again and its ok i've did it and play some games wi fi is enabled always i've use gps for 15 minutes and from yestarday till today so now i have 82% batt so i thing this is the best for batt
oh by the way lag fix is enabled to
Thank you. Do you know if calibrating the battery is useful even if I have one extra battery and I switch between the two batteries if necessery?
I don't know about the two battery thing, but i do agree that Project V have great battery life. Im using Super Dragon Modz kernel OCed to 1.3, and the phone its doing pretty nice till now. I unplugged it like 2 hours ago, and it still show 100%. On CM7, i would be around 75 to 80% by now. Battery life was the reason that i came back to Froyo.
WOW that's great battery life! Thanks a lot.
i don't konw about 2 batteries but calibrating is usefull it's helping 98% bug after unplug and it's greating a new battstat file what is realy nice project v6 is very good rom for battery i did't tried super dragon
I don't see how callibrating the battery helps extend battery life? The battery remains at the same capacity and draining any battery completely shortens the lifespan of the battery. I can see that the system might get a better prediction of battery life... But you get that regardless after using the phone for a few days / week...

I bought the 2000mah extended battery kit to my S2. Since the charge is so slow on the S2(about 3-4hours) I can't top it up when I get home before I go out again. So I'm thinking about using the original battery and pop that in when I get home.
But how will the phone and battery indicator react to me constantly switching between two different sized batteries? Will it completely mess it up? Would it help if I wipe the battery stats every time I put in a new battery? Cause I thought a phone needed a couple of charges to learn the capacity of the battery?
Is all i do is to swap battery as needed
Wipe battery stats only if i want to read new battery stats .
Wipe battery stats plays no part in the calibration of SGS2 battery .
jje
no it won't get messed up
Weird, I thought the phone needed to learn the battery before accurately displaying the battery levels.
But then I dont need to worry then.
Thanks for the fast replies!
I have an att galaxy s3 (d2att) that I got back in March 2013. Over the course of the year I have probably changed my rom about 20-30 times to get the perfect rom. Now my phone's screen time is about 1 hour while just letting it sit with the display on and not running any apps or touching it. Currently running the task650 rom with android 4.4.3. Wiping the battery stats file or running the calibration app does not work. There is no option in my recovery menu under advanced settings to wipe battery stats and a battery calibration app says the battery file does not exist. Sometimes the phone will turn off at about 30% and the reason I believe for that is that the voltage goes down so much. On time I checked it around 35-40% and it was at about 2.5V and then it shut down. When I charge it, it hovers around 3.9-4.3V but when I use it, it starts to go down like crazy. I don't know if I need a new battery or if I should completely factory reset my phone.
Any advice?

A bad battery can be really dangerous. It may have become like this because of bad use or overuse. I would recommend changing it asap

I don't see how flashing many ROMs could cause your battery life to drop. However the following issues are possible:
1) The ROM you are using has a bug that is causing some type of battery drain. These do happen.
2) You have charged and discharged your battery so many times that it cannot hold a charge anymore. I start noticing battery life decreasing after about 2 years of my usage (generally fairly low). Most times my battery life does not drop below 60% or so. If you very often let it drop very low, I can see the battery life decrease significantly after about a year.

Yea, I can only assume that because I have let it drop so low many times, I might have ruined the cells within. I might just end up buying a new battery. Thanks.
