Battery health greatly reduced
If maximum capacity is significantly degraded in your iPhone settings, autonomy and overall smoothness tend to worsen.
Service recommended message
When the system indicates need for service, it's a sign that the battery may no longer be functioning at its best.
Sudden drops in percentage
Sudden variations in charge are one of the most common signs of wear.
Unexpected shutdowns
Apps closing without reason or unexpected restarts may be related to an unstable battery.
Less autonomy
If you have to charge your iPhone much more often than before, the battery may no longer be responding as it should.
Excessive heating
Abnormal temperatures during use or charging deserve attention.
Swollen battery
This is an immediate warning sign. If you notice physical deformation, you should seek technical assistance as soon as possible.
