Battery temperature

A lithium-ion battery suffers from stress when exposed to heat and high charging voltages.A battery above 30 ° C (86 ° F) is considered elevated (but not critical), and for most Li-ion voltages above 4.10V per cell are considered high voltages. Elevated temperature accelerates the permanent loss of battery capacity. Not all Li-ion systems behave the same.

How to increase battery life of android phones:

Avoid charging the battery overnight.

Recharge your phone battery up to 80% instead.
Do not empty the Li-ion too low (charge your mobile device more often).
Random or partial charging is fine. Li-ion does not have to be fully charged.
Stop charging the battery when it is 80-90% charged.
Maintain between 30% and 80% of your mobile device's battery.
Lithium ion batteries DO NOT HAVE MEMORY so do not discharge and charge them to the end!Never completely discharge the battery!
Use fast chargers only if your mobile device is cold because the high temperature has a negative effect on the battery. (Warm / cool the battery to room temperature before charging)
Do not charge the battery when the temperature is below zero.
Use quick chargers only if your battery is designed (intended) for use.
Do not use your mobile device while the battery is charging, as this will raise the battery temperature and risk damaging the charger connector.
Reduce the charging current.
Avoid ultra-fast charging and heavy charging.Keep the battery cool.
Keep it away from heat-generating environments.
Avoid hot cars and window sills that are exposed to the sun.

The worst situation is keeping a fully charged battery at elevated temperatures.
Our app displays:
😱 when the battery temperature is below 22 ° C (71.6 ° F)
😎 when above 22 ° C (71.6 ° F) and below 33 ° C (91.4 ° F)
😢 when above 33 ° C (91.4 ° F) and below 43 ° C (109.4 ° F)
🤯 when the temperature is above 43 ° C (109.4 ° F)

Every phone has protection against battery overheating, battery temperature above 50 ° C (122 ° F) is dangerous!

Battery life is affected by:

Battery charging speed.
Maximum and minimum battery charge level.
Load (battery discharge rate).
Exposure to adverse temperatures.
Partial discharge reduces stress and extends battery life, as well as partial charge.
Elevated temperature and high currents also affect cycle life.

All Android mobile devices send only two notifications for the battery by default, when the battery charge is 100% or below 15%. To keep the battery in the optimal charge range, without constantly looking at the phone and checking the status, you need a application Battery Alarm.The basic version of the Battery Alarm app is ad-free, all major features are free. The application does not use the Internet, GPS, gsm, does not use critical Android licenses and is 100% secure and does not endanger the privacy of users.
