Moto G does not start, LED light turns on when charging

If you own a Moto G mobile phone, do not let its battery run down to zero. If you just did, try to charge it as usual. If the phone does not start up when you press and hold the Power button for a few seconds, don't worry. This is a known issue and can be fixed easily.

Use a more powerful charger to kickstart charging

The phone needs a higher Ampere current than the one provided by Moto G's charger. Find a charger that is rated 1.5A - for example, a charger that came with a tablet (or a bigger, more recent phone).

Charge the phone for 30 minutes and then press and hold the Power button till the phone turns on. If it doesn't, just leave the phone(battery) to cool for a day - yes, it needs that much time as I found out. Then, try again. Repeated attempts at charging without cooling the battery may damage it for good, so beware.

(I really hope you have a backup phone, a basic model that works with your SIM. Usually, access to your contacts is the main thing you need - which should be available on the internet if you sync/back up contacts. For example, Android phones might be synced to Google Contacts)

Once the phone starts up, you can go back to charging with Moto G's charger (the one with lower Ampere rating) since that's a better way to stretch your battery's life (on the other hand, if this didn't work, Motorola has advice for you - see https://forums.motorola.com/posts/3d5eadc25d).

How to charge your phone for a long battery life

In future, remember to charge your phone when it discharges to 40%. Stop charging when it reaches 100% or when it's in the 90s. Don't leave it charging after it reaches 100% since the charger discharges for a while after it reaches 100% and then charges it back to 100% - this repeats till you switch off the charger. For a more detailed explanation, see this page.

Find the time your phone requires to charge a single percentage point. For example, my Moto G charger needs 3 minutes for this. Depending on the charge left, estimate the time required for charging and only charge as long. Well, set a countdown timer if you would rather not remember!
