iOS 11.4 and iOS 11.3 is reported with poor battery life by many users who upgraded their iPhone to
latest iOS 11.3. The battery life is very poor in ios11.3 as the battery drain
really fast. It is surprising that even with iOS 11.3 update, all of a sudden
caused battery to drain at least 3-5x faster than ever before for some users.
This is really annoying from apple that for every new iOS release the battery
life becomes poor for many iPhone users.
Almost all phones including iPhone x
and iPhone 8/7/6 have been reported to get affected with poor battery with
upgrade to iOS 11.4. And the battery drain is immense and consumption is too
high by system. It’s like in 3 minutes users is losing 5% of battery.
How to fix battery drain in iOS 11.3 and iOS 11.4:
To save
battery of iPhone first please check which app is actually consuming too much
battery .Go to Settings > Battery. To see how long each app has been open
and running in the background. If it is some third party app uninstall it and
check the performance. Or
1. Turn
wifi off: to make sure any major
sync (like photos would stop). Please check that any major cellular updates are
also turned off.
2. Turn
off Siri & Search indexing in Photos - to minimize the "risk"
of lots of background activity that might drain the battery. It is quite
possible that iOS 11.3 will be reading in the background the photos to try
indexing and clustering them in order to offer better search options
3. Try
setting Auto-Lock to a new value: system update might have set Auto-Lock to
Never so the screen never turned off.
4. Turn
off iCloud Drive in iPhone settings as this can be a potential battery
consuming task to sync all data of your iPhone
5. General
setting :Clear the safari history. Turn the iMessage off for about 10
seconds then back on. Now Goto-> cellular settings and toggled ALL settings
either off then on or on then off again depending on how they were originally
set. Now hard reboot the iPhone and
check the battery performance.
