This is regarding the T-Mobile (Huawei) Prism smartphone, but my inquiry is more of a general nature, so I hope this is the correct forum to place this in.
Both at home and at work, I'm within line-of-sight of T-Mobile towers, as a result, the phone always displays full bars, so signal is not an issue.
With a radio app (TuneIn) running during the day on the HSDPA network (although I stop the app when I leave my desk), the original OEM battery will go from roughly 100%, down to about 35% in perhaps five to six hours. The battery (Huawei HB5K1H) is the battery that came packaged with the phone and has a date of manufacture of October 30, 2012.
When I put the charger (also Huawei OEM) on the phone - with the phone remaining powered on, the LED light indicates where it is at in the charging process, mostly amber, but when it reaches 90%, the LED turns green. I've noticed on more than one occasion, when the phone reaches 90% or above, the LED will sometimes flip back to amber unexpectedly. When I turn the screen on, the % charged, has dropped to as low as 83% and this is without the phone doing anything.
Thinking there might be an issue with the battery, I put a different battery in the phone today, it's also the same Huawei OEM but with a manufacturing date of 2011. Repeating the same with the TuneIn app today, this other battery went from 100% down to 35% in only three hours. When I then placed the same OEM charger on the phone while powered on, it also did the same, it reached 90% or so in the process, then dropped below 90% causing the LED to flip from green back to amber.
It seems like the only way for the battery to reach 100% (full charge) again is to power off the phone when charging, which is what I normally do at home.
Could this be an issue with the batteries themselves, the charger, or even the phone itself, or maybe an issue with the operating system (it is running Gingerbread 2.3.6).
Thanks in advance.
