Help phone problem related to extended battery?

[chrisjm00]

So I'm on my second extended battery, and it does the same thing my other one did. When i put it on the charger it will charge fine, but once its fully charged up, about 15-20 minutes later, the battery icon in the taskbar goes from a charged battery to a battery outline with a question mark. It never changes during charging, only after the battery is fully charged. I'm on the stock rom, but rooted. Could it be an app messing the reading up, or a bad phone?

 

[chrisjm00]

Has anyone else experienced this?

Is it a Motorola extended battery? Only those work on your X. The cheap China batteries no longer work.

 

[chrisjm00]

Yes. I bought it from the Verizon store.

Since you're rooted, you could install Recovery on your phone, tap the top button to initialize it (only needed the first time), then tap the second button to reboot into recovery. From there, use the volume up/down buttons to navigate and the camera button to select an option. The back button does just that.

I'd start with deleting your cache partition, then go to advanced and delete your battery stats, then back until you get the option to reboot phone. It's best to do this with a fully charged battery but at this point I don't see any other option, except to throw it in VZW's hands.

The cache partition is temp files used to speed up your phone. Deleting both of these is safe. You won't notice any problem.

Don't do the factory reset since it restores your phone back to the way it was when you brought it home. It might fix the problem but you lose all the settings on your phone. Paid apps will eventually come back, but you should have a backup plan (Titanium Backup, etc) in place before attempting it.

Alright, I cleared my battery stats and deleted my cache. Its charging right now. Is it possible i just ended up with two bad batteries in a row? Or could it actually be my phone?

If this fixes it, I'd call it a glitch.

Are you on the OTA 340 version? I think 340 had some battery improvements as well (for FC's).

 

[chrisjm00]

Yeah I'm on .340. I updated as soon as i got the phone.

I frequently update to a rom or restore a nandroid backup (using recovery). If my phone is fully charged (still plugged in) and I'm in recovery, I'll delete the battery stats. O/w I can get battery FC's from the backup expecting something different from the battery controller. Clearing battery stats seems to fix that.

How long before you know if the problem is fixed?

Since you have recovery, you might as well install Rom Manager and use it to create/manage your backups.

 

[chrisjm00]

Its fully charged now. I don't know how long its been fully charged, probably only 5 minutes or so. I hope this fixes it. The battery seems to perform fine, its just sort of irritating.

 

[colchiro]

When you clear batt stats with an extended battery, you usually want to run your phone low the first time so it can calibrate, like to when it gives you a warning. O/W the % might not be accurate. I have the extended but don't usually don't worry about it.

 

[chrisjm00]

Well it just went back to the question mark. It seemed to be working for a while but it just changed.

 

[chrisjm00]

Is it worth calling Verizon and trying to get another dx sent out? It doesn't seem to affect the performance or anything so its more of just a quirk than anything else.

 

[colchiro]

Have you tried the original battery? Does that have the same problem?

You could use Rom Manger to create a backup (aka a nandroid) of your current setup, then do a factory reset and see if that fixes it. Worst case you could restore your backup again if that didn't help. If you got a new phone, you'd have the equivalent of the factory reset.

 

[chrisjm00]

I have the standard battery in now. I'm waiting to see if it does the same thing. Maybe I just got 2 bad extended batteries. I still have the receipt so i might just take it back and exchange it once more.

 

[chrisjm00]

Verizon exchanged my phone with a new one and it looks like its all good now. Guess I just had a bad X.

 

[colchiro]

Cool.
