So last night I downloaded a particular app for the first time.
Could be coincidence but…
- Noticed as I was going sleep that I wasnt connected to my WiFi, though in my bedroom it can be hit and miss.
- Put my phone on charge and at 4am unplugged it as it was fully charged.
- Got up at 6am and it was on 80%
- Got work at 7.30, 17%
- On charge all day, hovered between 13 and 17%.
- Changed battery, no effect.
- Cannot log onto my WiFi, keeps saying ‘cannot connect’ and ‘incorrect password’ even though I’m entering the correct one.
- Back of phone red hot.
- Phone dipped to 2% at 4.30pm, been on charge 6 hours, only on 26%.
Anyone any ideas before I launch it at the wall??
Thanks in advance

Most issues like this can be resolved by simply turning off the device and then charging it with the original wall charger/cable for at least 4-6 hours or until fully charged. You must leave it switched off until fully charged! However if it gets very warm during this time try the network reset, this will possibly be the solution that works best however we must eliminate all others first as below.
1. Bad Connection
In areas with poor or reduced connectivity, iPhone has to expend more time searching for and maintaining network connections. This in turn uses more energy which causes the battery to heat up.
You can try turning
Airplane Mode on and see if you have the same problem with heating up. I also have an iPhone and I myself notice that it does not heat up if I am out in the open, but it heats up and drains the battery if I am in the basement of a large concrete building.
If you have a case for your iPhone, you should expect that it heats up. The case, while it does protect your phone, also blocks some air from coming out and consequently causes the hot air to be trapped inside the phone. This will cause your iPhone to heat up almost indefinitely.
When you are charging your iPhone, take it out of its case. While this may be inconvenient, it will help.
3. CPU Usage
If your phone is heating up, you may have a lot of applications open. Also, if you were playing a lot of games, then you can expect an increase in CPU usage and temperature as well.
All of the listed items below can contribute to an increase in CPU Usage:
- Data Usage (Facebook, Emails)
- Fetch/Push Data
Network Connections Reset(Go to Settings => General => Reset => Reset Network Settings, then reboot (you will lose WiFi passwords)
Try disabling the following apps (in Settings => General => Restrictions): Multiplayer Games, Ping, App Store, iTunes Store. Then reboot.
If nothing else works, then it is also quite possible that your iPhone is defective and if this continues to occur as you have stated, I would take it to an Apple Store. They may be able to better diagnose the problem.
