Solution 9: Enable Airplane Mode And Use Wi-Fi In Locations With Poor Network
If you are outdoor and in a location with a poor cellular network, then in such place you must use Wi-Fi if any secure Wi-Fi network is available instead using your cellular data plan.

So, in order to avoid iPhone battery drain,
