If you're storing your phone unused for an extended amount of time, it is advisable to keep the battery charged at 50 percent before turning it off for storage. For even longer periods, they recommend turning on the phone every six months or so and plugging it in to charge it back to 50 percent.
Why your iPhone battery dies with 50% left. So your iPhone battery icon on the top right of your screen might show 50%, even when it's about to die. To fix the problem, Apple suggests iPhone owners restart their phones, then go to Settings > General > Date & Time and make sure that "Set Automatically" is turned on.
It may be that the battery is bad. One of the symptoms of a bad battery is an immediate power off (meaning it doesn't go through the full shutdown process) before reaching zero, but I will say doing so at 70% is the most extreme case I've seen.
Applications are the first reason for this problem. So uninstall the apps. If problem has been happening after updating apps, then uninstall the updates. Software updates may be a reason for this problem.
The most common cause of phone turning off automatically is that the battery doesn't fit properly. With wear and tear, battery size or its space may change a bit over time. Make sure the battery side hit on your palm to put pressure on the battery. If the phone turns off, then it's time to fix the loose battery.
Google services aren't the only culprits; third-party apps can also get stuck and drain the battery. If your phone keeps killing the battery too fast even after a reboot, check the battery information in Settings. If an app is using the battery too much, Android settings will show it clearly as the offender.
7 ways to keep your dying Android phone or iPhone alive
- Turn your handset off and then on again. It's one thing if your phone's battery is dying simply because you've been using it all day without a break.
- Look for a battery-hogging app.
- Turn on Airplane mode.
- Turn on battery-saver mode.
- Carry an extra phone charger.
- Get a portable battery pack.
- Find a charging station.
High-drain apps - such as the camera - will often cause the device to die at even higher battery percentages - the problem started manifesting as dying at ~30% - but now it will sometimes die at 70%.
Why does my phone die when the battery percentage is over 10%? Is there a simple privacy law that actually makes sense? Most likely, because you've had it for a year or two, and your battery has worn out. Lithium ion batteries are like toner cartridges or printer ink.
The iPhone, like other smartphones do not use decimal for showing battery percentage. So when you are at 1% and if your battery usage indicator is not calibrated, you could be having a lot more juice than what is being shown to you (in this case the 1%).

The optimal place is for it to be between 40% and 80% as much as possible. So, if you're going for optimal, then you're letting it get way too low and then charging it way too high. That said, that's only giving you 40% of the battery to work with, so you're charging more often, etc.
As they age, the voltage sag becomes worse, to the point of no longer being able to run a device despite having a higher resting voltage. That's what is happening with yours and why it shuts the phone down.
when u have drained ur battery completely and it shut down - try to plug it in and charge for a while so that it has enough juice to go into recovery. once in recovery clear the dalvik cache. once it is fully charged - switch it on and android system will recalibrate the battery which will very likely fix the issue.
Another way to check your Android phone's battery health is through the built-in “hidden menu.” Dialing “*#*#4636#*#*” opens a “hidden Android test menu,” designed for basic troubleshooting.
Google services aren't the only culprits; third-party apps can also get stuck and drain the battery. If your phone keeps killing the battery too fast even after a reboot, check the battery information in Settings. If an app is using the battery too much, Android settings will show it clearly as the offender.
In case of first option battery is drained when phone is completely shut off, then it is either some kind of phone technical issue, or your battery is old/failure and have very high self-discharging rate. If the losing battery is still too fast, probably the battery is also old or you need update OS.
1. Force Restart. If your iPhone or iPad keeps shutting down, won't charge, or keeps crashing, it might be time for a hard reset. Whether it's really shutting down on its own, or it's rapidly depleting the battery due to rogue processes or Wi-Fi or cellular radio activity, a hard reset can help.

One way to try recalibrating the battery sensor software is to charge up to 100%, then use the phone until it shuts down automatically from low battery. Then charge up again to 100%. Now see if the problem persists.
Hard Reset Your iPhone
One of the most common reasons why your iPhone keeps shutting off is because it's stuck in a restart loop, constantly shutting off, turning back on, shutting off again, and so on. By performing a hard reset, we may be able to break your iPhone out of that loop.A Faulty iOS Update Might Cause Your iPhone to Die Quickly
With that being said, sometimes glitches in iOS updates might cause your phone's battery to drain quicker than it should. If you're getting a lot less than that, your last iOS update might be the culprit.Step 1: Drain the iPhone to 0%, Charge to 100%
For many users, simply draining the iPhone battery all the way down to 0% (not just to the point of shutting down, but actually letting it completely drain) and then charging it back to 100% is enough to get the random shut-off problem to resolve itself.
