Can I change battery to the biger battery

Cramming a bigger battery with unoriginal specs is dangerous and could lead to overheating, fires, and even the battery itself exploding. Try to find a battery with identical specs, and keep your battery lasting you for a long time by not placing the phone in excessively hot or cold locations, by not fully discharging it, and charging it whenever possible. You cannot overcharge lithium-ion batteries. Rechargeable batteries have a limited number of charge cycles, but one charge cycle only counts when the battery is drained all the way to zero. So if I used 20% each day, but I fully recharged the battery each day, that would only be one charge cycle.
