Since this phone has an unremoveable battery I did some research to prevent de javu.
So I'll be sharing uncommon tips and tricks to prolong your battery to keep you going for up to 4 years and to preserve it's capacity for longer.
Remember, your battery is like a machine.The more you demand and the more you stress it the shorter it's life will be.
Life Cycle --> Amount of charges/discharges your battery will survive through before it's unuseable.
mV --> Voltage of your battery.It increases as you charge and decreases as your discharge.This means a charged battery has higher mV than a discharged battery.There are lowest and highest thresholds to mV that play a key role in prolonging battery life cycle.
Capacity --> 3200 mAH by default for our batteries.Lowers over time due to wear.
Battery Wear --> Batteries wear down over time.A battery that is weared down will have less capacity and less life cycle left compared to a factory new battery.This guide's ambition is to preserve higher capacities for longer and increase life cycle.
mV and Percentages
For our phone mV/Percentage can be seen below.
-->4.3 mV is 100% Charging to this level is like overcharging your battery.Wears the battery down noticeably.ESPECIALLYif you charge your phone over the night, it's a battery killer.
-->3.9 mV is 60% Charging to this level is like using your battery the way it was meant to be used.Prolongs battery life noticeably but come on, which one of you can leave the house with 60% juice in your battery? We'll try to avoid this percentage while reducing wear.
-->3.2 mV is 15% You should avoid discharging below this level as it will fasten wear.
What max. Percentage should I charge to?
-->4.1 mV is 80%-85% and it is said to double battery life cycle as compared to 100%.The 20%-15% tradeoff is totally worth it in long term and it's not as low as 60%.
Sure, you can charge to 100% if you are going on a long trip or you need the extra 20% juice.Thanks to sony we've got great battery life already so for daily usage 80% should do.
-->To make it easy and get notified when phone is charged to 85%, use this freely avaliable app.You can choose the percentage yourself and it even shows voltage values.
Open the app up > settings > battery charged settings > tick notify by percent > tap on percent of charge.Remember to launch the app before charging your phone.
Other important factors that effect battery life cycle :
The percentage to start charging at
You don't need to wait for your phone to discharge all the way down to 15%.Infact, recharging your phone and keep it between 40% - 80% where possible increases your battery's life cycle.Because you put less stress on the battery this way which reduces wear.
Li ions are known to have problems with difficult environmental conditions.Now there are some li ions with different chemistry which adapt nicely but they are used by military and stuff and not phones because they have tradeoffs.
Temperature can wear down your battery way faster than the cases above.Avoid heat at all times, to do so :
-->Charge your battery at cooler temperatures.Now room temps would do fine (try to not go below 10 C), just find the coolest room you can find and charge it.
-->Never use your phone while it's being charged.When a battery is getting charged and if you use your phone at the same time, you are basically charging and discharging at the same time which wears it down real quick.Also generates heat.
-->Never play demanding games under sunlight/in hot environments.Playing games alone does a good job heating the battery, sunlight added it's like frying your battery.
Image below only for mass effect fans :
Batteries get inaccurate about percentage and voltage over time.Mostly noticeable after two months of no calibration.However, calibrating once per 3 months should do fine.
-->Discharge your phone to 0% once per 3 months.It recalibrates it.Now you might ask "doesn't that increase wear?" It indeed does but without calibrating your phone at all you might aswell be only using 70-80% of your phone's actual battery capacity.
Sorry for repeating myself but remember, your battery is like a machine.The more you demand and the more you stress it the shorter it's life will be.
