Slow charging

[MasonG]

Anybody got any information on the slow charging problem? Before anybody states the obvious, fairly new device (around 2 months old) brand new 45watt oem samsung charger. (Bought yesterday) all settings are correct (power saving off. Battery protection off. Fast charging enabled) phones fully up to date. 

Phone still refuses to super fast charge. Won't even fast charge. Ran it through an app. Phones only pulling 5-8watts.

Is this a software or hardware problem?

Hi, and welcome to the community

Firstly what makes you think it's not fast charging.

When plugged into charger head to Settings>Device Care>Battery. What does it say? See screenshot.

Try a different known working cable / charger combination

Try a hard reset

With the device powered up, Hold the Volume down button and Power button simultaneously for 10 seconds. The screen will go off. Continue to hold buttons until the device vibrates and the Samsung logo appears. Release buttons. Device will reboot. Once done, please check if the issue is resolved.

Try Wiping cache partition

Plug into a working PC or laptop or other Samsung device

Just says 'charger connect' tried different cables and bricks, same problem. Just tried hard resetting and clearing the cache. The problem still persists

Possible I've just got a faulty device? Multiple different wires and bricks and still only pulls 5/8 watts

Thanks, it certainly sounds like a hardware fault.

Inspect your charging port with a torch. Blow out any debris or dust.

As a last resort before considering repair, then try a full factory reset. If still not resolved, then reach out to the retailer for support.

One thing you can try - go to Settings / Device care / Diagnostics / Phone diagnostics  ... and test Cable charging and Wireless charging (if that applies).

Tried that shows up fine. Charging speed says normal. I'm not sure if it should say super fast or anything

[Robin999]

Yes should say Super fast underneath

[MasonG]

Yeah just checked. I get superfast on my s23 ultra. Not on my s24 for some reason:/

That seems to rule out your cable / charger combo, then.

Don't know if it's worth it, but you could try it in Safe mode. This could rule out any 3rd party apps or customisations that might be causing your issue.

To get to Safe Mode - Long press Power button, long press Power off icon, tap Safe mode icon. (When booted into Safe mode, you may need to turn off flight mode as it sometimes enables itself). Check the charging status. If the issue is fixed, then you know it's one of your 3rd party apps or customisations that were the culprit. It's then up to you to determine which one by a process of elimination.

If still not resolved, then factory reset. When complete, don't use any backups or install any apps, just concentrate on the charging. If still not resolved, then seek retailer support.
