Wipe Battery Status

---

Hello Milestone users!

I am using Moto milestone for some time now and I have a question about battery calibration status. In NORMAL hacked recoveries there was an option "Wipe Battery Status". Of course in Open recover (got recovery and i guess adb recovery too) that option doesn't exist. I wonder if any of wipes available does something like battery status wipe? If so, does restoring nandroid system backup affect somehow battery capacity information? I'm asking because i get miserable battery life on single charge and i'm seeking for a reason (about 14h of well.. light usage...)

Sorry for any grammar/spelling mistakes, English is not my native language. I hope this post i readable

No worries: just open an adb shell and type the following.
mount -a
rm /data/system/batterystats.bin

The battery stats are stored in the mentioned .bin file!

According to my personal experience, whenever you flash a rom which is basically different from the one you are going to remove, it is useful to wipe the battery stats and charge the phone to its full capacity.
This is generally valid for all the android phones.

Thank you, Sir! I was not aware of that script I will try that for sure, but I guess I will still have to visit my carrier and send my milestone on warranty.. Come on... 14 hours? I can't plug it twice a day EVERY day..

Please do the proper test before sending your phone to the assistance.
Consider that the battery life depends on:
- your peculiar usage (do you listen to music or play games?)
- the number of active widgets which connect to the net
- the quality of radio signal of the area where you are
- the temperature...

Consequently, wipe the battery stats, charge the phone to its max capacity and come back here!

OK, if users don't mind I will "extend" this thread and complain about my battery;

In general it looks like this:
-Auto brightness always on
-3G always on
-google sync on
-exchange sync on
-weather sync once for 4 hours
-news sync once for 4 hours
-no data absorbing widgets (only weather bug)
-no games
-no music

Oh, and about signal quality.. I almost always am in good range of 3g/hsdpa network

Now, I don't surf internet alot, but I read news when I go to work and home. Screen is active total 2,5h a day and according to battery use built in android screen absorbs up to 75% of whole battery! (usually 60-66%)

I made some reaserch one day and I wiped whole phone, switched to edge, disabled exchange sync so I used stock settings. No apps, no additional data (only google account) and battery still made only 14h... That made me think, that something is not quite ok.. I had previously htc magic and battery was not an issue that I would consider as important. (I know bigger screen etc, but still...) If you think I am doing something wrong please advise

I will try your tip with battery ststus wipe in a minute and will give report tomorrow or day after

Thank you for your help! I appreciate it!

Don't want to disappoint you, but from the description of your usage 14 hours might be normal. Especially with 2.5h screen being on. Few advices: disable google sync (I assume you use exchange) you will get 10-15% more. Make sure you don't have widgets that update themselves set to update too often, remove the weather widget from screen (just for a day to see what gives), consider installing SetCPU for root users (free for XDA members) and define some profiles like lower CPU frequency while screen is off, or when you reach certain batterly levels (of course if you have root).

I also had a magic and, according to my experience, the Milestone's battery lasts as long as Magic's one, if not a little more.
Switching from HTC to Motorola did not affect my usage abits, and maybe it's the same for you, so I think the differences may be due to the battery itself.
Try changing it!

Are there other ways to wipe the battery status other than using ADB?
