Dell inspiron 15 7567 battery life

[austinadebote2000]

My Dell inspiron 15 7567 has a very poor battery performance. Meanwhile my brothers exact same model bought together with mine has a much better performance

If you are doing the exact same tests to check for battery life, contact Dell, that system should be in warranty. Make sure you are checking the same programs and same screen brightness when you check battery life.
