Calibrate Battery?
- Thread starter Kobe24
- Start date
Calibration apps aren't going to give the metering system what it needs to determine the battery's maximum and minimum voltages so it can properly gauge what the interim levels are. You need to "show" the meter by letting it read those levels right from the battery.
Since every battery has a unique signature and unique maximum capacity the only way the charging system can possibly know is by witnessing the battery in action. The only way to do that is by charging to 100% with power off followed by discharging to 15% (10% with Jelly Bean). The subsequent charge to 100% confirms the full range to the meter and locks the range in its data store to recall from for future level calculations.

I had a pretty accurate battery meter until I installed my new Motorola Extended Battery. I haven't been able to get a "good calibration" from the battery despite trying to calibrate the battery. I tried using the calibration tool and charged and discharged my phone and despite a month or so of use it still seems to jump around. Even tonight, if I look at my battery monitoring app the charge is slow and steady, then jumped 9% in 1 minute. Go figure. It's not that big of a deal(aside from the fact that I want it to be accurate) since the battery lasts so long that I haven't had the battery get critically low.
Im having this problem with my bionic 4000 extended battery. Gone through so many cycles going to completely dead battery or just about hour before it dies but it still wont seem to calibrate

I've done exactly what Foxkat says. I did alot of forum reading and stuff before I jumped into the realm of battery calibration. Still have an odd battery meter. I am rooted and I did use one of those "battery calibration" programs to wipe the old battery parameters. I can tell from using both of the batteries that my standard battery had a 100% charge of 4.351v and the extended is only 4.201v. So there are slight differences between batteries.
Anyway, I may try doing a calibration again just to see if I can get better luck the second time.

It seems that the best extended battery for the Bionic is the one made by Motorola in that the software plays nicely with it. I use the Bada$$ Battery Monitor (substitute 'ss' for '$$') as FoxKat recommends and it's accurate with the Motorola extended battery.
When I had my OG Droid, I had a Seidio extended battery. No app would give a real reading, even Battery Left, which had a setting for the Seidio. In the end I used the Battery Left widget, but as it could give 3 lines of information, I put Voltage on top. I knew that if it was 4200mv it was charged and around 3500mv it was time to find a charger.

Boyfriend's having the same problem with the Seido 4000mAh battery. He's let it discharge and then charged up with the phone off several times, and it still stays on 1% for like 20 hours before it finally dies.

The heck with calibration. Tried them all, it still doesn't show correctly. Get the battery monitor widget. When my battery reads 3200 mV, I know the end is a few minutes away. Getting around 16-18 hours out of my vzw extended battery, using savings settings. Shut off data and Wi-Fi when not in use. Love the slimmer size(2760) vs the 4000, which is now sitting in my drawer.
