Why is my nexus 5x draining battery so quickly?

[AC Question]

My battery lasts a maximum of around 32 hours when put into flight mode. It's lucky to last 24 hours even if I don't touch the phone all day. Battery stats only show a small percentage being used. I had the same problem with the original battery, bought a new replacement which has not helped at all. What could be causing the battery to drop charge?

Welcome to the forums. What version of Android are you on?

Thanks
Currently on version 7.1.2
Problem has been ongoing for months, through several upgrades. Think the last time I saw normal battery life was while using Marshmallow. Phone has been charged to 100% 24 hours ago, has lost 73% but only stat on battery use is mobile standby at 3%.

How old is the battery?

Replacement battery is a couple of months old. This battery is showing no improvement over old battery so I assume it's some other problem.

Have you tried reflashing the ROM?

That mobile standby - tap the grid to get to the next page, then look at the bottom for the mobile signal. Is it solid green? If not, the weak signal is costing you battery. Even if you're in the same place, the carrier may have moved the pattern on the towers, making the signal weaker where you are. (That's why it's a good idea to keep an eye on the signal strength every month or so. If the carrier isn't supplying you with enough signal in the places you normally are, you may need a different carrier. (Saving money, or getting a nice free phone, doesn't end up doing you much good if that carrier is going to cause your battery to drain fast.)

Another thing to remember - as we keep getting newer versions of Android, they keep doing more, costing more battery. 7.1.2 uses a lot more battery than 2.3.3 did.

I wouldn't even know where to start with this!

Sorry that should read phone idle. Had phone on airplane mode at the time. Battery can be fully charged but even if phone is switched off completely the battery still discharges. Had the same issue with both batteries.

On the 5X, this should be pretty easy, and even though the video is a few years old, the steps are similar. You will need to unlock the bootloader, which will wipe the device.
