A Galaxy A35 charges at 25 W, which owners measure at roughly eighty minutes for a full charge, and the complaints on Samsung's forums are of a phone that charges slowly after an update and more slowly again after the latest one. Samsung's own reply is to use a genuine Samsung charger and check the cable for damage, and that is the right first step because the A35 needs a 25 W PD PPS adapter for its fastest charge. A plain 5 W or 10 W brick, a thin cable or a wireless pad that the A35 does not have all lead to slow charging; the A35 has no wireless charging. If it will not charge at all, clean the USB-C port and check Protect battery.

0 of 6 completedUse Samsung's own 25 W charger and cable
ReversiblePlug the genuine Samsung 25 W adapter and a 3 A cable into a wall socket, which is exactly what Samsung's support reply tells owners with slow charging to do first.
Look at the cable and the port
ReversibleInspect the cable for fraying and the USB-C socket for lint; with the phone off, ease out packed fluff with a wooden toothpick, scraping the walls and not the center tongue.
Check the 85 percent protection
ReversibleSettings, Battery, Protect battery: Maximum stops the A35 near 85 percent, which owners sometimes mistake for a charging fault.
Charge idle and cool
ReversibleTake the case off and leave the phone alone on a hard surface; a warm A35 slows its own charge.
Restart and test in Safe mode
ReversibleRestart, then charge in Safe mode for twenty minutes; if the percentage rises, an installed app was holding the phone back.
Run the charging test

Model-specific
What is true of this model and not of its siblings
- How to time your own charge
- Plug in at ten percent with the screen off and note the time you reach one hundred; the A35 with Samsung's 25 W adapter should take roughly eighty minutes, and a charge of two hours or more means the adapter, the cable or heat is the limit.
- A cable test
- Charge the A35 with a cable from another phone that charges at full speed; if the time drops, the first cable was the problem.
Stop boundary
When this stops being a self-service repair
- !If a Samsung charger and cable fail with a clean port, book a Samsung repair
- !If charging slowed after an update, report it with the version
- !A hot or swollen phone must go to service

Common questions
Can I use a laptop charger on the A35?+
It will charge the phone, but only a PD PPS adapter gives the 25 W rate.
Why does the A35 stay warm while charging?+
Charging at 25 W makes heat inside a thin phone; a case and use while charging add to it.
