Battery protection: charging stopped
Samsung Galaxy Battery protection: charging stops before 100%
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Your Galaxy stops charging before 100% because Battery protection is on. It is a setting, not a fault. Open Settings > Battery > Battery protection and choose Basic, Adaptive or Maximum, or turn it off when you need a full charge.
Safety first
Stop and check this first
- If you turn protection off and leave the phone at 100% for long periods, Samsung explains that the battery's lifespan can shorten.
Safe checks you can perform
- See which protection option is on
- Change the option when you need a full charge
- Check the software version
Leave these tasks to a qualified professional
- Do not attempt this professional task: Samsung Support if it stops below the chosen limit
- Do not attempt this professional task: Battery check at a Samsung service centre

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
See which protection option is on
- Who:
- you.
- How:
- open Settings > Battery > Battery protection and check whether it is on and which option is selected.
- Result that matters:
- whether the level where charging stops matches the option.
- If it stops at 80% with Maximum, or 100% then 95% with Basic:
- the setting is doing its job.
- If it stops at a level no option explains:
- try another genuine charger and contact Samsung.
- Evidence to keep:
- Screenshot of the Battery protection screen.

Change the option when you need a full charge
- Who:
- you.
- How:
- in Battery protection choose Basic or turn the feature off before a day when you need 100%, then charge again.
- Result that matters:
- whether the phone now charges to 100%.
- If it does:
- the protection was the only reason it stopped.
- If it still stops early with protection off:
- contact Samsung Support.
- Evidence to keep:
- Option chosen and level reached.

Check the software version
- Who:
- you.
- How:
- check whether your phone has One UI 6.1 or later. On older versions the only protection limits charging to 85%.
- Result that matters:
- which protection your software offers.
- If it is older than One UI 6.1 and stops at 85%:
- that is the expected limit.
- If it is One UI 6.1 or later:
- use the three options above.
- Evidence to keep:
- One UI version.

What it means
Samsung explains that keeping the battery at 100% for a long time can reduce its lifespan, so One UI 6.1 offers three options. Basic stops at 100% and starts charging again when the level drops to 95%. Adaptive uses Maximum while you sleep and switches to Basic before you wake. Maximum stops charging at 80%. On software below One UI 6.1 the only option is to limit the charge to 85%. A charge that stops at one of these levels is the setting working, not a battery or charger fault.
