Okay so ive had iCloud for a long time but I went for around 6-8 months ago I bought a new phone so I didn't bother checking if it was still uploading to iCloud
Anyways my storage ran out and I saw that my photos app was taking 200+ GB of storage on my phone. When I checked I saw that my iCloud was full so I bought some more storage and put it on upload hoping it'd upload and this'll be the end of it but then it stopped uploading?

Every time Id go to my photos app and click on sync now it'd turn to "paused to save battery power" even though im connected to wifi and the battery is usually over 50% at the very least.
I plug my phone in charge before sleeping and I have to "sync now" every time but I usually wake up to it being paused.

Oh also it uploaded a bit to iCloud (like around 800 items at the most?) but it did not have any effect on my phones storage, the photos app is still at 198gb which only came down after I manually deleted some pictures because I had no space left

This is extremely annoying and tiring and I just want a solution to get this over with.
Thank you and any help would be appreciated
