[SOLVED] Problems with battery

[Martin2027]

Hi

I've had a problem with my 3 phones. I've bought a Pixel 3a, had no problems with it and after 2 months of use the max battery capacity went down by 8 % so I returned the phone and got a different Pixel 3a. The second phone had the same problem just after 2 days. Now I have the OnePlus 7T and after a month of use my max battery capacity went down by 9%.

I barely fast charge my OnePlus, mostly I use a regular iPhone charger. I don't charge it overnight, I usually unplug the phone when it hits 80%, I don't let the battery get bellow 15%, the phone is not hot when it's charging (it's hot only when fast charging) so I really don't know what could be the issue.

Please help, I really don't know what I am doing wrong.

Why are you even using an iPhone charger to charge these phones?

Whatever kind of device you are charging, it's always best to use the charger that came with or a spare that's approved for use with it as they were designed and tested for use with that device.

So if your device is damaged by something your manufacturer has no control, its mainly your fault.

Agreed to @kerangovender. This is something how I've damaged my iPhone 7. I wasn't using a certified Apple charger and instead was buying cheaper ones. I couldn't use the phone for more than 5 hours just because the battery would drain from 100 % to 10 %. Sometimes the level of battery would drain even if I have the airplane mode enabled! Learnt from my mistakes, now using iPhone XS along with the original Apple charger - so far no complaints. So yeah, please consider changing your charged to an original one, and you will be astonished of the results, thats for sure
