@Jonathan_Bondu: I would highly recommend to give the “Battery Software Reset” a try, because this is exatly the (temporarly) solution for your described problems!
So please: try it once (or twice) and report back if you could improve it a little!!
After 2 years usage, I am far away from having a dying battery because it still lasts 3-4 days for my average usage, while I try from time to time the Battery Reset, which is by the way no big deal!
Some more points about this:
Battery drops appear repeatedly at FP (also after doing the Battery Reset) if you
- put battery off the phone and back in
- if you switch your phone off and on frequently
- if you switch of your phone with a low level (<20-30%)
- If your battery usage is not limited to only 20-80% but also involves from time to time 0-100%
So you shoud avoid these points in general, but mor important escpecially after doing a Battery Reset to keep a good battery health for a longer time.
After each of the above scenarios a “BatteryReset” should give you a quite more accurate Battery calibration and thus the possibility to just use more of its capacity, which otherwise just is not recognised by the Fairphone-Software!
But in very serious cases, you could also have a dying, while aged battery, but I think it should be only your conclusion, after you first tried the points above!
