Assuming you would like tips on how to better monitor your battery charge:
One way to help monitor and prolong the life of your battery is by calibrating it regularly. To do this, first discharge your battery until it shuts off automatically. Once it’s shut off, recharge it fully without interruptions until your device indicates it’s fully charged. Then, use your device as usual until it needs another charge.
It’s also important not to let your battery drain completely before recharging, as this can shorten its lifespan. Try to keep the charge between 40-80%. If you must let it drain completely, make sure to recharge as soon as possible afterwards.
Additionally, avoid extreme temperatures if possible, both hot and cold. Both can damage batteries permanently and cause them to degrade quicker. If you must store your device in either a hot or cold environment for an extended period of time (like during winter), make sure the battery has at least a 40% charge beforehand.
You can also help improve your battery life by reducing its screen brightness and turning off any unnecessary features or apps when not in use
