MacBook air brand new battery only last 2 hours

i have a late 2013 13" MacBook Air, the battery has 50 cycles, I've changed the thermal paste and completly cleaned the inside it looks brands new, I've just formatted and installed macOS Monterey.

Yet with all that and no prgroam running but Google Chrome, the fan makes more noise than an airplane, and heats up a lot! and It also last 2 hours on battery. What should I do?

It doesn't seem buying a new battery will fix it, is it just me or the rest of the world?

thank you for your help

Well, the battery and the charging logic both look good at the surface. But, batteries do lose there ability to hold a charge with age! As you can see this battery is still the original one the system was sold with. So it does look like you do need a battery. Batteries last about 5~6 years at best just from age.

But you likely have a second issue here and thats using both macOS Monterey and Chrome! Both are heavy RAM & Storage hogs.

This system RAM is either 4 or 8GB which is quite low for todays OS's and apps. To add to it the SSD storage can be quite low! 128GB, 256GB, or 512GB so you do need to limit your expectations on what this system can offer you.

At this point I would reduce as much as I can of content (data) and applications you really don't need so you free up as much storage space. I would also forget about Chrome and go back to a lighter Web browser like Safari. If thats not possible then you'll need to look at increasing your storage to 512 if not larger. That will help but the real limit is the RAM if you have only a 4GB system there's not much you can do.

Maybe it's time to get a newer system (new o used)? 16GB and 512GB/1TB of storage.

Well, I'm happy to hear you have 8GB of RAM and a more sizable 512GB drive.

But the battery is older than you think! You could try doing a hard SMC reset to see if that alters things. Follow the MacBook Air 13" Mid 2013 Battery Replacement guide to Step 3 so the battery is fully disconnected. Now with nothing plugged in press and hold the power button so you can fully discharge the logic board, a good 15sec's is whats needed. Now leaving the battery disconnected plug in the MagSafe charger the system should spontaneously startup, let it finish booting up, then do a clean shutdown. Now plug back in the battery and restart the system again. Let the system idle for a good 5 minutes with the MagSafe also plugged in. Now take a fresh CoconutBattery snapshot and post it here, also expand the battery info window as well.
